Definitions
- the present invention relates to 4-aryl-l-difluoromethoxyimidazoles of the formula I.
- R 1 is hydrogen, Cx-Cj-alkyl or C 1 -C 4 haloalkyl
- R 2 is hydrogen, halogen, cyano, C 1 -C 4 -alkyl or C 1 -C 6 -haloalyl;
- R 3 is a 5- or 6-membered aromatic radical which optionally has one, two or three heteroatoms selected from oxygen, nitrogen and sulfur, which is optionally substituted and / or a further fused, 5- or 6-membered group carbocyclic or heterocyclic ring having 1 to 3 heteroatoms, selected from nitrogen, oxygen and sulfur atoms, wherein the fused ring is partially or completely unsaturated, unsubstituted or in turn can carry one, two or three substituents, and / or can contain one or two non-adjacent carbonyl, thiocarbonyl or sulfonyl ring members,
- WO 94/17059 and WO 99/05125 herbicidally active compounds which have a phenyl-substituted heterocycle.
- Substituted imidazoles can be used as heterocycles.
- EP 590 843 describes 4-phenylimidazoles, the 6 haloalkyl, a C -Cs-alkenyl nyl- or at the imidazole nitrogen, a Ci-Cio-alkyl, C ⁇ -C is a C 3 -C 5 alkynyl group may have, and their use as herbicides.
- the object of the present invention was to provide new arylimidazoles with which undesired plants can be controlled more effectively than before.
- the task also extended to the provision of new desiccant / defliantly effective connections.
- the object is surprisingly achieved by 4-aryl- (1H) -imidazoles which carry a difluoromethoxy group in the 1-position of the imidazole ring.
- the present invention therefore relates to the 4-aryl-l-difluoromethoxyimidazoles of the general formula I defined at the outset and their agriculturally acceptable salts.
- the invention also relates to the use of compounds I and their salts as herbicides and / or for the desiccation and / or defoliation of plants, herbicidal compositions and agents for the desiccation and / or defoliation of plants which the compounds I and / or their salts are effective Contain substances, process for the preparation of the compounds I and herbicidal agents and agents for desiccation and / or
- the compounds of the formula I can have one or more centers of chirality in the substituents and are then present as enantiomer or diastereomer mixtures.
- the invention relates both to the pure enantiomers or diastereomers and to their mixtures.
- Agriculturally useful salts include, in particular, the salts of those cations or the acid addition salts of those acids whose cations or anions do not adversely affect the herbicidal activity of the compounds I.
- Anions of useful acid addition salts are primarily chloride, bromide, fluoride, hydrogen sulfate, sulfate, dihydrogen phosphate / hydrogen phosphate, phosphate, nitrate, hydrogen carbonate, carbonate, hexafluorosilicate, hexafluorophosphate, benzoate, and the anions of C 1 -C 4 -alkanoic acids, preferably Formate, acetate, propionate and butyrate. They can be formed by reacting I with an acid of the corresponding anion, preferably hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid or nitric acid.
- All carbon chains ie all alkyl, haloalkyl, phenylalkyl, cycloalkylalkyl, alkoxy, haloalkoxy, alkylthio, haloalkylthio, alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, haloalkylsulfonyl, alkenyl -, Haloalkenyl, alkynyl and haloalkynyl groups and corresponding parts of groups in larger groups such as alkoxycarbonyl, phenylalkyl, cycloalkylalkyl, alkoxycarbonylalkyl etc.
- Halogenated substituents preferably carry one, two, three, four or five identical or different halogen atoms.
- Halogen is fluorine, chlorine, bromine or iodine.
