to a process for the preparation ol` and to the use of those compounds and tautomers, to
pesticidal compositions in which Lhe active ingredienl has been selected from those
compounds and laulomers, in e~ch case in free form or in the form of an agrochemically
2139~65
- 3
acceptable salt, and to a process for the preparation of and to the use of thosecompositions.
Certain hydrazone derivatives are proposed in the literature as insecticidally active ingre-
dients in pesticides. The biological properties of those known compounds are not,
however, entirely satisfactory in the area of pest control and, therefore, there is a need to
provide further compounds having pesticidal properties, especially for the control of
insects, ectoparasites and representatives of the order Acarina. This problem is solved
according to the invention by the provision of the present compounds I.
Some of the compounds I may be in the form of tautomers. If, for example, R2 is H,
corresponding compounds I, that is to say those having a -N(H)-C(R3)=X partial structure,
may be in equilibrium with the respective tautomers having a -N=C(R3)-XH partialstructure. Accordingly, hereinafter there is to be understood by compounds I, where
applopliate, also corresponding tautomers, even if the latter are not specifically mentioned
in every case.
The compounds I and, as the case may be, their tautomers may be in the form of salts.
Compounds I having at least one basic centre may form, for example, acid addition salts.
These are formed, for example, with strong inorganic acids, such as mineral acids, e.g.
sulfuric acid, a phosphoric acid or a hydrohalic acid, with strong organic carboxylic acids,
such as unsubstituted or substituted, for example halo-substituted, C1-C4alkanecarboxylic
acids, e.g. acetic acid, saturated or unsaturated dicarboxylic acids, e.g. oxalic, malonic,
maleic, fumaric or phthalic acid, hydroxycarboxylic acids, e.g. ascorbic, lactic, malic,
tartaric or citric acid, or benzoic acid, or with organic sulfonic acids, such as unsubstituted
or substituted, for example halo-substituted, C1-C4alkane- or aryl-sulfonic acids, e.g.
methane- or p-toluene-sulfonic acid. Compounds I having at least one acid group may
furthermore form salts with bases. Suitable salts with bases are, for example, metal salts,
such as alkali metal salts and ~lk~line earth metal salts, e.g. sodium, potassium or
magnesium salts, or salts with ammonia or an organic amine, such as morpholine,
piperidine, pyrrolidine, a mono-, di- or tri-lower alkylamine, e.g. ethylamine, diethyl-
amine, triethylamine or dimethylpropylamine, or a mono-, di- or tri-hydroxy-lower alkyl-
amine, e.g. mono-, di- or tri-ethanolamine. Furthermore, corresponding internal salts may
also be formed. Within the scope of the invention, agrochemically advantageous salts are
preferred; also included, however, are salts that have disadvantages for agrochemical
applications, for example salts that are toxic to bees and ~o t`ish, which can be used, for
213g465
example, for the isolation and purification of free compounds I or their agrochemically
acceptable salts. In view of the close relationship between the compounds I in free form
and in the form of their salts, hereinbefore and hereinafter any reference to the free
compounds I or their salts is to be understood as including also the corresponding salts or
the free compounds I, respectively, where appropriate and expedient. The same applies to
tautomers of compounds I and their salts.
Unless defined otherwise, the general definitions used hereinbefore and hereinafter have
the meanings given below.

Salts of compounds I can be prepared in a manner known per se. For example, acidaddition salts of compounds I are obtained by treatment with a suitable acid or a suitable
ion-exchange reagent, and salts with bases are obtained by treatment with a suitable base
or a suitable ion-exchange reagent.
Salts of compounds I can be converted into free compounds I in customary manner: acid
addition salts, for example, by treatment with a suitable basic agent or a suitable ion-
exchange reagent, and salts with bases, for example, by treatment with a suitable acid or a
suitable ion-exchange reagent.
Salts of compounds I can be converted into different salts of compounds I in a manner
known per se: acid addition salts, for example, can be converted into different acid
addition salts, for example by treatment of a salt of an inorganic acid, such as a hydro-
chloride, with a suitable metal salt, such as a sodium, barium or silver salt, of an acid, for
example with silver acetate, in a suitable solvent in which an inorganic salt being formed,
for example silver chloride, is insoluble and therefore separates from the reaction mixture.
Depending upon the procedure and the reaction conditions, compounds I having salt-
forming properties can be obtained in free form or in the form of salts.
The compounds I, II, III and IV may be in the form of one of the possible isomers or in the
form of a mixture thereof; for example, depending upon the number and the absolute and
relative contiguration of the asymmetric carbon atoms, they may be in the form of pure
isomers, such as antipodes and/or diastereoisomers, or in the form of mixtures of isomers,
such as mixtures of enantiomers, for example racemates, mixtures of diastereoisomers or
mixtures of racemates; lhe invention relates both to the pure isomers and to all possible
2139465
- 24 -
mixtures of isomers and this is to be understood hereinbefore and hereinafter, even if
stereochemical details are not specifically mentioned in every case.
Mixtures of diastereoisomers and mixtures of racemates of compounds I, II, III and IV that
are obtainable in accordance with the process - depending upon the starting materials and
procedures chosen, - or by other means, can be separated into the pure diastereoisomers or
racemates in known manner on the basis of the physico-chemical differences between the
constituents, for example by fractional crystallisation, distillation and/or chromatography.
Mixtures of enantiomers, such as racemates, accordingly obtainable can be separated into
the optical antipodes by known methods, for example by recryst~llic~tion from anoptically active solvent, by chromatography on chiral adsorbents, for example high-
pressure liquid chromatography (HPLC) on acetylcellulose, with the aid of suitable micro-
org~nicm.s, by cleavage with specific immobilised enzymes, or via the formation of
inclusion compounds, for example using chiral crown ethers, in which case only one
enantiomer is complexed.
Apart from by the separation of corresponding mixtures of isomers, it is possible
according to the invention to obtain pure diastereoisomers or enantiomers also by
generally known methods of diastereoselective or enantioselective synthesis, for example
by carrying out the process of the invention with starting materials having correspondingly
suitable stereochemistry.
Advantageously, the biologically more active isomer, for example enantiomer, or mixture
of isomers, for example mixture of enantiomers, will be isolated or synthesised, insofar as
the individual components have differing biological activity.
The compounds I, II, III and IV can also be obtained in the form of their hydrates and/or
may include other solvents, for example solvents that have been used, where appropriate,
for the crystallisation of compounds that are in solid form.

The good pesticidal activity of the compounds of the invention corresponds to a mortality
of at least 50 to 60 % of the mentioned pests.
The activity of the compounds according to the invention and of the compositionscomprising them can be substantially broadened and adapted to prevailing circumstances
by the addition of other insecticides. Examples of suitable additives are representatives of
the following classes of compounds: organophosphorus compounds, nitrophenols andderivatives thereof, t`ormamidines, ureas, carbamates, pyrethroids, chlorinated
hydrocarbons and Bacillus thuringiensis preparations.
The compounds according lo the invention are used in unmodified form or, prel`erably,
2139465
- 28 -
together with the adjuvants customarily employed in formulation technology and can
therefore be formulated in known manner e.g. into emulsifiable concentrates, directly
sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders,
dusts, granules, and also encapsulations in polymer substances. As with the nature of the
compositions, the methods of application, such as spraying, atomising, dusting, scattering
or pouring, are chosen in accordance with the intended objectives and the prevailing
circumstances.
The formulations, i.e. the compositions, preparations or mixtures comprising thecompound (active ingredient) of the invention or a combination thereof with other
insecticides, and, where appropriate, solid or liquid adjuvants, are prepared in known
manner, e.g. by homogeneously mixing and/or grinding the active ingredient with the
adjuvants, such as extenders, e.g. solvents or solid carriers, or surface-active compounds
(surfactants).
Suitable solvents are: aromatic hydrocarbons, preferably alkylbenzene fractions containing
8 to 12 carbon atoms, such as xylene mixtures or alkylated naphthalenes, aliphatic or
cycloaliphatic hydrocarbons, such as cyclohexane, paraffins or tetrahydronaphthalene,
alcohols, such as ethanol, propanol or butanol, glycols and their ethers and esters, such as
propylene glycol, dipropylene glycol ether, ethylene glycol, ethylene glycol monomethyl
or monoethyl ether, ketones, such as cyclohexanone, isophorone or diacetanol alcohol,
strongly polar solvents, such N-methyl-2-pyrrolidone, dimethyl sulfoxide or N,N-di-
methylformamide, water and vegetable oils or epoxidised vegetable oils, such as rape oil,
castor oil, coconut oil or soybean oil or epoxidised rape oil, castor oil, coconut oil or
soybean oil; and, where appropriate, silicone oils.
The solid carriers used, e.g. for dusts and dispersible powders, are normally natural
mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to
improve the physical properties it is also possible to add highly dispersed silicic acids or
highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous
types, such as pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent
carriers are calcite or sand. ln addition, a great number of granulated materials of
inorganic or organic nature can be used, especially dolomite or pulverised plant residues.
Depending upon the nature of the compound of the invention or of the combination of that
compound with olher inseclicide~ which is lo be formulated, suitable surface-active
2139 165
- 29 -
compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying,
dispersing and wetting properties. The term "surfactants" will also be understood as
comprising mixtures of surfactants.
Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cyclo-
aliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, said derivatives
containing 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydro-
carbon moiety and 6 to 18 carbon atoms in the aLkyl moiety of the alkylphenols. Further
suitable non-ionic surfactants are water-soluble adducts of polyethylene oxide with poly-
propylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol
containing 1 to 10 carbon atoms in the alkyl chain, which adducts contain 20 to 250
ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. These
compounds usually contain 1 to 5 ethylene glycol units per propylene glycol unit. Repre-
sentative examples of non-ionic surfactants are nonylphenol polyethoxyethanols, castor oil
polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxy-
ethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Fatty acid esters of
polyoxyethylene sorbitan, e.g. polyoxyethylene sorbitan trioleate, are also suitable
non-ionic surfactants.
Cationic surfactants are preferably quatern~ry ammonium salts which contain, as
N-substituent, at least one C8-C22alkyl radical and, as further substituents, unsubstituted or
halogenated lower alkyl, benzyl or hydroxy-lower alkyl radicals. The salts are preferably
in the form of halides, methyl sulfates or ethyl sulfates. Examples are stearyltrimethyl-
ammonium chloride and benzyldi(2-chloroethyl)ethylammonium bromide.
Both so-called water-soluble soaps and water-soluble synthetic surface-active compounds
are suitable anionic surfactants. Suitable soaps are the alkali metal salts, alkaline earth
metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C10-C22),
e.g. the sodium or potassium salts of oleic or stearic acid or of natural fatty acid mixtures
which can be obtained e.g. from coconut oil or tall oil; mention may also be made of fatty
acid methyltaurin salts. More frequently, however, so-called synthetic surfactants are
used, especially fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or
alkylarylsulfonates. The fatty sulfonates or sulfates are usually in the form of alkali metal
salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and
generally contain a C8-C22alkyl radical, which also includes the alkyl moiety of acyl
radicals; there may be mentioned by way of example the sodium or calcium salt of ligno-
213gl65
- 30 -
sulfonic acid, of dodecyl sulfate or of a mixture of fatty alcohol sulfates obtained from
natural fatty acids. These compounds also comprise the salts of sulfated or sulfonated
fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably
contain 2 sulfonic acid groups and one fatty acid radical containing approximate ly 8 to 22
carbon atoms. Examples of aL~cylarylsulfonates are the sodium, calcium or triethanol-
ammonium salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid or of a
condensate of naphthalenesulfonic acid and formaldehyde. Also suitable are corres-
ponding phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol
with 4 to 14 mol of ethylene oxide, or phospholipids.
The surfactants listed above are to be regarded merely as examples; many more
surfactants customarily employed in formulation technology and suitable for use
according to the invention are described in the relevant literature.
The pesticidal compositions usually comprise 0.1 to 99 %, preferably 0.1 to 95 %, of a
compound of the invention or of a combination of that compound with other insecticides,
and 1 to 99.9 %, preferably 5 to 99.9 %, of a solid or liquid adjuvant, it generally being
possible for 0 to 25 %, preferably 0.1 to 20 %, of the composition to be surfactants
(percentages are by weight in each case). Whereas commercial products will preferably be
formulated as concentrates, the end user will normally employ dilute formulations which
have considerably lower active ingredient concentrations. Typical concentration rates are
from 0.1 to 1000 ppm, preferably from 0.1 to 500 ppm, active ingredient. The application
rates per hectare are generally from 1 to 1000 g of active ingredient per hectare, preferably
from 25 to 500 g/ha.
Preferred formulations have especially the following composition (throughout,
percentages are by weight):
Emulsifiable concentrates:
active ingredient: 1 to 90 %, preferably 5 to 20 %
surfactant: 1 to 30 %, preferably 10 to 20 %
liquid carrier: 5 to 94 %, preferably 70 to 85 %

active ingredient: 0.1 to 10 %, preferably ().1 ~o 1 /0
solid carrier: ')').9 to 90 %, preferably 99.9 lo 99 %

Suspension concentrates:
active ingredient: 5 to 75 %, preferably 10 to 50 %
water: 94 to 24 %, preferably 88 to 30 %
surfactant: 1 to 40 %, preferably 2 to 30 %

active ingredient: 0.5 to 90 %, preferably 1 to 80 %
surfactant: 0.5 to 20 %, preferably 1 to 15 %

Granules:
active ingredient: 0.5 to 30 %, preferably 3 to 15 %
solid carrier: 99.5 to 70 %, preferably 97 to 85 %
The compositions may also comprise other adjuvants, such as stabilisers, e.g. vegetable
oils or epoxidised vegetable oils (e.g. epoxidised coconut oil, rape oil or soybean oil),
antifoams, e.g. silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, as
well as fertilisers or other active ingredients for obtaining special effects.

Preparation Examples
General Remarks
The compounds are obtained as isomeric mixtures usually in the form of viscous oils.
They can be purified by column chromatography. NMR spectra and elemental analyses
confirm the required structures.
Example P1: 4-chloro-4'-trifluoromethanesulfonyloxybenzophenone-N-methylhydrazone
180 g of 4-chloro-4'-trifluoromethanesulfonyloxybenzophenone are heated under reflux in
600 ml of absolute alcohol with 29.6 g of glacial acetic acid and 31.8 g of methyl-
hydrazine for one day. The solution is then concentrated by evaporation in vacuo, and the
residue is taken up in approximately 150 ml of toluene and again concentrated by evapora-
tion. The oil which remains is taken up in hexane/ethyl acetate '): l and the solution is
2139~65
- 32 -
stirred over magnesium sulfate and sodium bicarbonate for approximately 30 minutes.
The salts are removed by filtration and the filtrate is concentrated by evaporation in vacuo.
The title compound remains behind in the form of a yellow oil.
Example P2: 4-chloro-4'-trifluoromethanesulfonyloxybenzophenone-N-formyl-N-methyl-
hydrazone (compound 1.1 in Table 1)
With the exclusion of moisture, 150 g of sodium formate are introduced into approxi-
mately 125 ml of ether with stirring, and 147 g (1.87 mol) of acetyl chloride are added
dropwise thereto at a reaction temperature of 0C. The reaction mixture is then stirred for
several hours at room temperature, sodium chloride is removed by filtration, and the
residue is washed with dry ether to yield a solution of approximately 1.87 mol of forrnyl
acetate in ether.
A portion of that solution, containing 0.49 mol of formyl acetate, is added dropwise to a
solution of 184 g of the hydrazone from Example P1 in 200 ml of ether. The reaction is
complete after a few hours. Ice-water is added, the organic layer is collected, washed
once more with water, dried over magnesium sulfate and filtered, and the f1ltrate is
concentrated by evaporation and purified by column chromatography on silica gel using
ethyl acetate/hexane 1:9 as eluant. The product is obtained as an isomeric mixture in the

Biolo~ical Examples
Example B 1: Action against Diabrotica balteata
Maize seedlings are sprayed with an aqueous emulsion comprising 400 ppm of test
compound. After the spray coating has dried, the maize seedlings are populated with 10
Diabrotica balteata larvae in the second stage and then placed in a plastics container.
6 days later, the percentage reduction in the population (% activity) is determined by
comparing the number of dead larvae on the treated plants with that on untreated plants.

3 days later, the percentage reduction in the population and the percentage reduction in
feeding damage (% activity) is determined by comparing the number of dead caterpillars
and the feeding damage on the treated plants with that on untreated plants.
Compounds of Tables 1 to 4 exhibit good activity in this test. In particular, compounds 1.1

more than 80 % effective.
Example B5: Action against Spodoptera littoralis
Young soybean plants are sprayed with an aqueous emulsion comprising 400 ppm of test
compound. After the spray coating has dried, the soybean plants are populated with 10
Spodoptera littoralis caterpillars in the third stage and then placed in a plastics container.
3 days later, the percentage reduction in the population and the percentage reduction in
feeding damage (% activity) is determined by comparing the number of dead caterpillars
and the feeding damage on the treated plants with that on untreated plants.
Compounds of Tables 1 to 4 exhibit good activity in this test. In particular, compounds
1.1 to 1.22, 1.77 to 1.80, 1.126 to 1.129, 1.132, 1.134, 1.175 to 1.178, 1.183, 1.195 to

covered with a cottonwool ball, and 10 ml of aqueous test solution comprising 125 ppm of
active ingredient are poured over the ticks. The cotton wool ball is removed, and the ticks
are incubated for 4 weeks for oviposition. The action becomes apparent either, in the case
of the female, in the form of mortality or sterility or, in the case of the eggs, in the form of
an ovicidal action.
Compounds of Tables 1 to 4 exhibit good activity in this test. In particular, compound
1.204 is more than 80 % effective.
Example B7: Action against Blattella germanica
A solution (0.1 %) of the active ingredient in acetone is placed into a Petri dish in such an
amount that this corresponds to an application rate of 1 g/m2. When the solvent has
evaporated, 10 nymphs of Blattella germanica (last nymphal stage) are placed in the dish
and exposed to the action of the test substance over 2 hours. The nymphs are then
anaesthetised using CO2, transferred to a fresh Petri dish and kept in the dark at 25 and
circa 70 % atmospheric humidity. After 48 hours, the insecticidal action is determined by
calculating the destruction rate.
In this test, compounds of Tables 1 to 4 exhibit good activity. In particular, compounds
1.61, 1.186 and 3.03 are more than 80 % effective.
Example B8: Action against Musca domestica
A sugar lump is treated with such an amount of test substance that the concentration of
test substance in the sugar is 250 ppm after drying overnight. The lump which has been
treated in this manner is placed on an aluminium dish together with a wet cotton wool ball
and 10 adults of an OP-resistant strain of Musca domestica. The dish is covered with a
glass beaker and incubated at 25. The mortality rate is determined after 24 hours.
In this test, compounds of Tables 1 to 4 exhibit good activity. In particular, compounds
1.61, 1.186 and 3.03 are more than 80 % effective.
