The present invention relates to certain new N-(1,3-
azolyl)-alkyl-halogenoacetanilides, to a process for their
preparation and to their use as herbicides.
It has already been disclosed that 2,6-diethyl-N-methoxy-
methyl-chloroacetanilide can be used for selectively combating
weeds (see R. Wegler, Chemie der Pflanzenschutz- und
Il ll
Schadlingsbekampfungsmittel (Chemistry of Plant Protection Agents
and Agents for Combating Pests), volume 5, page 255, Springer-
Verlag (1977)). However, this compound is not always sufficiently
active and its selectivity is not always completely satisfactory.
The present invention now provides, as new compounds,
the N-~1,3-azolyl)alkyl-halogenoacetanilides of the general
f ormul~ CN ~
R2 1 ~ CH2 - z (I)
in which
A represents oxygen or sulphur
Rl represents hydrogen, alkyl or alkoxy,
R represents hydrogen, alkyl, al]coxy or halogen,
R3 represents hydrogen, alkyl, alkoxy or halogen,
R4 represents hydrogen or alkyl,
X represents hydrogen, alkyl, halogen, alkoxy,
alkylthio, halogenoalkyl, alkoxycarbonyl, dialkyl-
amino or cyano,
;
8524
X represents hydrogen, alkyl, halogen, alkoxy,
alkylthio, halogenoalkyl, alkoxycarbonyl, dialkyl-
amino or cyano, and
Z represents halogen,
and the azolyl radical is bonded via a carbon atom, and
acid addition salts and métal salt complexe.~, thereof.
The N-(1,3-azolyl)alkyl-halogenoacetanilides of the formula
(I) and acid addition salts and metal salt complexes thereof have
powerful herbicidal properties, in particular selective herbicidal
properties.
Preferably, in formula (I)1
Rl represents hydrogen or straight-chain or branched alkyl
or alkoxy with in either case 1 to 4 carbon atoms,
R2 and R3, which are identical or dierent, each represent
hydroyen~ straight-chain or branched alkyl or alkoxy with in either
case 1 to 4 carbon atoms, fluorine, chlorine or bromine,
R4 represents hydrogen or alkyl with 1 to 4 carbon atoms,
xl and X2, which are identical or different, each represent
hydrogen, straight-chain or branched alkyl with 1 to 4 carbon atoms,
straight-cha.in or branched alkoxy with 1 to 4 carbon atoms,
straight-chain or branched alkylthio with 1 to 4 carbon atoms,
alkoxycarbonyl with 1 to 4 carbon atoms in the alkoxy group,
fluorine, chlorine, bromine, halogenoalkyl with up to 2 carbon
atoms and up to 5 identical or diferent halogen atoms (preferred
halogens being fluorine, chlorine and bromine), dialkylamino with
1 to 4 carbon atoms in each alkyl part or cyano, and
Z represents chlorine, bromine or iodine.

The invention also provides a process for the preparation
of an N-(1,3-azolyl)-alkyl-halogenoacetanilide of the formula (I),
or an acid additio.n salt or metal salt complex thereof, in which
(a) an N-(1,3-azolyl)alkyl-aniline of the general formula
X
H (II),
R
in which
A, R , R , R , R , X and X have the meanings stated above,
is reacted with a halogenoacetic acid chloride or bromide or
anhydride of the general formula
Z-CH2-CO-Cl~Br) (IIIa)
and
(Z-cH2-c)2 (IIIb),
in which
Z has the meaning stated above,
in tne presence of a diluent and if appropriate in the presence of
an acid binding agent, or
(b) a halogenoacetanilide of the general formula
R3 ~ \ C - C}l2 - Z ~IV),
in which
Rl, R2, R3 and Z have the meanings stated abov~,
is reacted with an azolyl-alkyl derivative of the general formula

Y - CH ~ (V),
in which
A, R4, Xl and x2 have the meanings stated above
and
Y represents halogen or the mesy:Late or tosylate
radical,
in the presence of an acid-binding agent and if appropriate
in the presence of an organic solvent, and
an acid or a metal salt is then optionally added
10 onto the compound (I) produced in either variant (a) or (b).
Surprisingly, the posslbilities of using the N-(1,3-
azolyl)alkyl-halogenoacetanilides according to the invention,
which ha~e a very good herbicidal action, as agents for
selectively combating weeds in important crop plants are
15 better than those of using 2,6-diethyl-N-methoxymethyl-
chloroacetanilide, which is known from the state of the art
and is an active compound of high activity and the same type
of action. The substances according to the invention
thus represent a valuable enrichment of the art.
Particularly preferred N-(1,3-azoIyl)alkyl-halogeno-
acetanilides of the formula (I) are those in which A
represents oxygen, sulphur or the grouping ~NR, R representing
methyl, ethyl, propyl or butyl; Rl represents hydrogen,
methyl, ethyl, isopropyl, sec.-butyl, tert.-butyl, methoxy,
; 25 ethoxy or isopropoxy; R and R3, which are identical or
different, each represent hydrogen, methyl, ethyl, isopropyl,
sec.-butyl~ tert.-butyl, methoxy, ethoxy, isopropoxy,
chlorine or bromine; R4 represents hydrogen or methyl;
xl and X2, which are identical or different, each represent
30 hydrogen, methyl, ethyl, n-propyl, isopropyl, n-butyl,
sec.-butyl, tert.-butyl, methoxyl ethoxy, isopropoxy, methyl-
thio, ethylthio, isopropylthio, methoxycarbonyl, ethoxy-

Further preferred compounds according to the in-
ve.ntio~ are also addition products of acids and those N-(1,3-
azolyl)al~yl.-halogenoacetanilides of the formula (I) in which
A, R, Rl, R2, R3, R4~ Xl, x2 and Z have the meanings which
have already been mentioned as preferred therefor. The
acids which can be added on include, as preferences, hydrogen
halide acids (for example hydrobromic acid and, in particular,
hydrochloric acid), phosphoric acid, nitric acid, sulphuric
acid~ monofunctional and bifunctional carboxylic acids and
hydroxycarboxylic acids(for example acetic acid, maleic

acid, succinic acid, fumaric acid, tartaric acid~ citric acid,
salicylic acid, sorbic acid and lactic acid)~ and sul-
phonic acids (for example p-toluenesulphonic acid and
1,5-naphthalenedisulphonic acid).
Yet further preferred compounds according to the
invention are addition products of salts of metals of main
groups II to IV and of sub-groups I and II and IV to VIII
and those N-(1,3-azolyl)alkyl-halogenoacetanilides of the
formula (I) in which A, R, Rl, R2, R3, R4~ Xl, x2 and Z
have the meanings which have already been mentioned as
pre~erred therefor. Salts of copper, zinc, manganese,
magnesium, tin, iron and nickel are particularly preferred
here. Preferred anions of these salts are those which
are derived from those acids which lead to physiologically
acceptable addition products. In this connection,
particularly preferred acids of this type are the hydrogen
halide acids (for example hydrochloric acid and hydrobromic
acid), phosphoric acid, nitric acid and sulphuric acid.
If 2,6-dimethyl-N-(2'-methylthiazol-4'-yl-methyl)-
aniline and chloroacetyl chloride are used as starting sub-
stances in process variant (a)~ the course of the reaction
can be represented by the following equation:

If 2-ethyl-6-methyl-chloroacetanilide and ~-bromo-

The formula (II) provides a general definition of
the N-(1,3-azolyl)alkyl-anilines required as starking sub-
stances in carrying out process (a) according to the
invention. In this formula, A, Rl, R2, R3, R4, Xl and x2
preferably have those meanings which have already been
mentioned as preferred therefor in connection with the
description of the substances of the formula (I) accord-
ing to the invention.
The following compounds may be mentioned as specific
examples of compounds of the formula (II):

substances in the preparation of the N-(1,3-azolyl)alkyl-
anilines of the ~ormula (II) are generally known compounds
of organlc chemistry. Examples which may be mentioned
are: aniline, 2-methylaniline, 2-ethylaniline, 2-isopropyl-
aniline, 2-sec.-butylaniline, 2-tert.-butylaniline, 2,6-
dimethylaniline, 2,3-dimethylaniline, 2,5-dimethylanlline,
3,5-dimethylaniline, 2,6-diethylaniline, 2-ethyl-6-methyl-
aniline, 2~3,4-trimethylaniline, 2,4,6-trimethylaniline,
2,4,5-trimethylaniline, 2-ethyl-4,6-dimethylaniline, 2,6-di-
iO ethyl-4-methylaniline, 2,6-diisopropyl-4-methylaniline,
2,3,5-trimethylaniline, 2,3,6-trimethylaniline, 2-methyl-6-
chloroaniline, 2-tert.-butyl-6-chloroaniline, 2-methoxy-6-
methylaniline, 2,6-dimethoxyaniline, 2-methoxy-6-ethyl-
aniline and 2,6-diethoxyaniline.
The azole-aldehydes of the formula (VII) also required
as starting substances in the preparation of the N-(1,3-
azolyl)alkylanilines of the formula (II) are known (see,
for example, J. Am. Chem. Soc. 61, 891 (1939); Acta Chem.
Scand. 20, 2J600 (1966) and Helv. Chim. Acta 3L~, 147 (1959)),
or they can be obtained by the processes described in the
literature.
Any of the customary acid acceptors can be used as
acid-binding agents in the preparation of the N-(1,3-
azolyl)alkylanilines of the formula (II) by process ().
Alkali metal carbonates, such as potassium carbonate or
sodium carbonate, are preferably used.
Diluents which can be employed in process () are
any of the customary inert organic solvents. Dimethyl-
formamide and toluene are preferably used.
The reaction temperatures can be varied within a
substantial range in process (a). In general, the
reaction is carried out between 0C and 180C, preferably
between 20C and 160C.
In general, the anilines of the formula (VI) and
~5 the azolylalkyl derivatives ofthe formula (V) are employed
Le A 19 123
- 52 -
in equimolar amounts in the reaction in process (~).
However, it is also possible to employ one of the components,
preferably the aniline of the formula (VI), in excess.
Working up and isolation of the reaction products are
effected by customary methods (see the preparative examples
given later).
Inert or~anic solvents which can be used in the
first stage in the preparation of the N-(1,3-azolyl)alkyl-
anilines of the formula (II) by process (~) are any of the
customary solvents of this type. Aromatic solvents, such
as toluene, are preferably used.
Catalysts which can be used in the first stage in
reaction (~) are any of the reaction accelerators customary
for addition reactions of this type. Strong organic
acids, such as ~-toluenesulphonic acid, are preferably used.
Any of the inert polar organic solvents can be used as
the solvent in the second stage of process (~). Alcohols,
such as methanol, are preferably used.
Complex hydrides, for exampl0 sodium borohydride,
can preferably be used as the reducing agent in carrying
out the second stage of process (~).
The reaction temperatures can be varied within a
substantial range both in the first stage and in the
second stage in carrying out process (~). In the first
stage, the reaction is in general carried out at tempera-
tures between 40C and 140C, preferably between 60C
and 120C. In the second stage, the reaction is in
general carried out at temperatures between -10C and
+lQ0C, preferably between 0C and 80C.
In general, the anilines of the formula (VI) and
the azole-aldehydes of the formula (VII) are employed in
equivalent amounts in carrying out process (~). However,
it is also possible to employ one o~ the components,
preferably the aniline of the formula (VI), in excess.
The reducing agent required in the second stage is
Le A 19 ~23
~,
.
~L~2~352
- 53 -
appropriately employed in excess. Working up and isolation
of the reaction products are in each case effected by
customary methods (see the preparative examples given
later).
The formulae (IIIa) and (IIIb) provide general
definitions of the halogenoacetic acid chlorides and
bromides and anhydrides also to be used as starting sub-
stances for process variant (a) according to the invention.

ammonium or phosphonium compound, benzyl-dodecyl-dimethyl-
ammonium chloride (Zephirol) and triethyl-benzyl-ammonium
chloride being mentioned as examples (see also the pre-
parative examples herein).
The substances of the formula (I) accordi~g tothe invention, whether prepared by process variant (a) or
by process variant (b), can be converted into acid addition
salts and metal salt complexes.
The following acids are preferably used for the pre-
paration of physiologically acceptable acid addition salts

ion.
The active compounds according to the invention
influence plant growth and can therefore be used as
defoliants, desiccants, agents for destroying grasses and
broad-leaved plants, germination inhibitors and, especially,
as weed-killers. By "weeds" in the broadest sense there are
meant plants growing in places where they are not desired.
Whether the compounds according to the invention
act as total herbicides or selective herbicides depends
essentially on the amount used.
The active compound~ according to the present in-
vention may be used, for example, to combat the followingplants:

The active compounds according to the pre.sent i.nvention
may be used, for e~ample, as selective herbicides in the
~ollowing cultures:
dicotyledon cultures of the genera ~ossypium,
Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum,
Ipomoea, Vicia, Nicotiana, Lycopersi~con, Arachis,
Bras-sica, Lactuca, Cucu~is and'Cucurbi'ta; and
monocotyledon cultures o~ the genera ~yza, Zea,
Triticum, Hordeum, Avena, Secale,' ~ hum, Panicum,
Saccharum, Ananas, Asparagus and Allium.
However, the use of the active compounds according
to the invention is in no way restricted to these genera
but also embraces other plants, in the same way.
Depending on the concentrations, the compounds can
be used for the total combating of weeds, for example
on industrial terrain and railway tracks and on paths
and squares with or without trees. Equally, the compounds
can be employed for combating weeds in perennial cultures,
for example afforestations, decorative tree plankings,
orchards, vineyards, cltrus groves, nut orchards, banana
plantations, co~fee plantations, tea plantations, rubber
plantations, oil palm plantations, cacao plantations, soft
fruit plantings and hopfields, and for the selective combating
of weeds in annual cultures. '
In addition to a very good action against graminaceous
weeds and against varieties o~ , the active compounds
according to the invention also exhibit, in particular, a
good herbicidal action on broad-leaved weeds. It is
possible to use the active compounds according to the
30 invention selectively, preferably on cereals, rape-seed, l:
cotton and sugar beet.
The active compounds can be converted to the custom- .
ary ~ormulations, such as solutions, emulsions, wettable
poweders, suspensions, powders, dusting agents, pastes,
soluble powders, granules, suspension-emulsion concentrates,
natural and synthetic materials impregnated with active

compound, and very fine capsules in poIymeric substances.
These formulations are produced in known manner, for
example by mixing the active compounds with extenders, that
is to say liquid or solid diluents or carriers, optionally
with the use of surface-active agenks,that is to say
emulsifying agents and/or dispersing agents and/or foam-
forming agents. In the case of the use of water as an
extender, organic solvents can, for example, also be used
as auxiliary solvents.
As liquid diluents or carriers, especially solvents,
there are suitable in the main, aromatic hydrocarbons,
such as xylene, toluene or alkyl naphthalenes, chlorinated
aromatic or chlorinated aliphatic hydrocarbons, such as
chlorobenzenes, chloroethylenes or methylene chloride,
aliphatic or alicyclic hydrocarbons, such as cyclohexane
or paraffins, for example mineral oil fractions, alcohols,
such as butanol or glycol as well as their ethers and
esters, ketones, such as acetone, methyl ethyl ketone,
methyl isobutyl ketone or cyclohexanone, or strongly
polar solvents, such as dimethylformamide and dimethyl-
sulphoxide, as well as water.
As solid carriers there may be used ground natural
minerals, such as kaolins, clays, talc, chalk, quartz,
attapulgite, montmorillonite or diatomaceous earth, and
ground synthetic minerals, such as highly-dispersed silicic
acid, alumina and silicates. As solid carriers for granules
there may be used crushed and fractionated natural rocks
such as calcite~ marble, pumice~ sepiolite and dolomite,
as well as synthetic granules of inorganic and organic
meals, and granules of organic material such as sawdust,
coconut shells, maize cobs and tobacco stalks.
As emulsifying and/or foam-forming agents there
may be used non-ionic and anionic emulsifiers, such as
polyoxyethylene-fatty acid esters, polyoxyethylene-fatty
alcohol ethers, for example alkylaryl polyglycol ethers,
~,
Le A 19 123
~2~52
- 63 -
alkyl sulphonates, alkyl sulphates, aryl su~phonates as
well as albumin hydrolysis products. Dispersing agents
include, for example, lignin sulphite waste liquors and
methylcellulose.
Adhesives such as carboxymethylcellulose and natural
and synthetic polymers in the form of powders, granules
or latices, such as gum arabic, polyvinyl alcohol and
polyvinyl acetate, can be used in the formulations.
It is possible to use colorants such as inorganic
pigments, for example iron oxide, titanium oxide and
Prussian Blue, and organic dyestuffs, such as alizarin
dyestuffs, azo dyestuffs or metal phthalocyanine dyestuffs,
and trace nutrients, such as salts of iron, manganese,
boron, copper, cobalt, molybdenum and zinc.
The formulations in general contain from 0.1 to 95
per cent by weight of active compound, preferably from
0.5 to 90 per cent by weight.
The active compounds according to the invention, as
such or in the form of their formulations, can also be
used, for combating weeds, as mixtures with other herbi-
cides, finished formulations or tank mixing being possible.
Mixtures with other active compounds, such as ~ungicides,
insecticides, acaricides, nematicides, bird repellants 3
growth factors, plant nutrients and agents which improve
soil structure, are also possible.
The active compounds can be used as such, in the
form of their formulations or in the use forms prepared
therefrom by further dilution, such as ready-to-use solutions,
suspensions,~emulsions, powders, pastes and granules. They
may be used in the customary manner, for example by watering,
spraying~ atomising and scattering.
The active compounds according to the invention can
be applied either before or after emergence of the plants.
They are preferably used before emergence of the plants,
that is to say by the pre-emergence process. They can
,

also be incorporated into the soil before sowing.
The amount of active compound used can vary within
a substantial range. It depends essentially on the nature
of the desired effect. In general, the amounts used are
from Ool to 10 kg of active compound per hectare, preferably
from 0.1 to 5 kg/ha.
The present invention also provides a herbicidal
composition containing as active ingrecLient a compound
of the present invention in admixture with a solid diluent
or carrier or in admixture with a liquid diluent or carrier
containing a surface-active agent.
The present invention also provides a method of com-
bating weeds which comprises applying to the weeds, or
to a habitat thereof, a compound of the present invention
alone or in the form of a composition containing as active
ingredient a compound of the present invention in admixture
with a diluent or carrier~
The present invention further provides crops protected
f'rom damage by weeds by being grown in areas in which
immediately prior to and/or during the time of the growing
a compound of the present invention was applied alone
or in admixture with a diluent or carrier.
It will be seen that the usual methods of providing
a harvested crop may be improved by the present invention.
The herbicidal activity o~ the compounds of this
invention is illustrated by the following biotest Example.
In this Example, the compounds according to the
present invention are each identified by the number (given

To produce a suitable preparation of active compo~d,
l part by weight of active compound Wa5 mixed with the
s~ated amount of solvent, the stated amount of emulsifier
was added and the concentrate was diluted with water to
the desired concentration.
Seeds of the test plants were sown in normal soil
and, after 24 hours, watered with the preparation of
the active compound. It was expedient to keep constant
the amount of water per unit area. The concentration
of the active compound in the preparation was of no import-
ance, only the amount of active compound applied per
unit area being decisive. After three weeks, the degree
of damage to the plants was determined in % damage in
compari~on to the development o~ ~he untreated control.
The figures denoted:
0% = no action (like untreated control)
