3-CYANOARYL PYRAZOLES AND USE THEREOF AS HERBICIDES

摘要

The invention relates to novel 3-cyanoaryl pyrazoles of the general formula (I) in which Q is oxygen (O), sulphur (S), SO or SO2, R<1> is hydrogen or possibly substituted alkyl, alkenyl, alkinyl, cycloalkyl or cycloalkyl alkyl, R<2> is hydrogen or possibly substituted alkyl, alkenyl, alkinyl, cycloalkyl or cycloalkyl alkyl, R<3> is hydrogen, halogen or possibly substitued alkyl, R<4> is hydrogen or halogen, and R<5> is hydrogen, hydroxy, mercapto, amino, hydroxyamino, halogen or one of the radicals -Q-R<6>, -NH-R<6>, -NH-O-R<6>, -NH-SO2-R<6>, -N(SO2-R<6>)2, -CQ<1>-R<6>, -CQ<1>-Q<2>-R<6>, -CQ<1>-NH-R<6>, -Q<2>-CQ<1>-R<6>, -NH-CQ<1>-R<6>, -N(SO2-R<6>)(CQ<1>-R<6>), -Q<2>-CQ<1>-Q<2>-R<6>, -NH-CQ<1>-Q<2>-R<6> or -Q<2>-CQ<1>-NH-R<6> where Q<1> and Q<2> are oxygen or sulphur and R<6> is possibly substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkyl alkyl, aryl, arylalkyl, heterocyclyl or heterocyclyl alkyl, where the compounds 1-methyl-3-(4-cyano-2-fluoro-phenyl)-4-chloro-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-fluoro-phenyl)-4-bromo-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-fluoro-5-nitro-phenyl)-4-chloro-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-fluoro-5-ethyl sulphonylamino-phenyl)-4-chloro-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-fluoro-5-ethoxy carbonyl methoxy-phenyl)-4-chloro-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-chloro-phenyl)-4-chloro-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-chloro-5-methylthio-phenyl)-4-chloro-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-fluoro-5-amino-phenyl)-4-chloro-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-fluoro-5-hydroxy-phenyl)-4-chloro-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-fluoro-5-chloro-phenyl)-4-chloro-5-difluoro methoxy pyrazol, 1-methyl-3-(4-cyano-2-fluoro-5-aminosulphonyl-phenyl)-4-chloro-5-difluoro methoxy pyrazol and 1-methyl-3-(4-cyano-2-fluoro-5-fluoro-sulphonyl-phenyl)-4-chloro-5-difluoro methoxy pyrazol are excepted by disclaimer; process for their production, novel intermediate products and the use of the 3-cyanoaryl pyrazoles as herbicides.
