Substituted phenylaminosulphonylureas A b s t r a c t The invention relates to new substituted phenylaminosulphonylureas of the formula (I) (I) in which R1 to R4 have the meanings given in the description and R5 represents alkyl having 1 to 8 carbon atoms which is optionally substituted by halogen, C1-C4-alkoxy, C1-C4-alkylthio, C1-C4-alkylsulphinyl or C1-C4-alkylsulphonyl, or represents cycloalkyl, cycloalkyl-C1-C4-alkyl, cycloalkenyl or cycloalkenyl-C1-C4-alkyl, each of which has 4 to 7 carbon atoms in the cycloalkyl or cycloalkenyl groups and each of which is optionally substituted by halogen and/or C1-C4-alkyl, or represents phenyl or phenyl-C1-C4-alkyl, each of which is optionally substituted by halogen, C1-C4-alkyl or C1-C4-halogenoalkyl, or represents heterocyclyl or heterocyclyl-C1-C4-alkyl having 2 to 6 carbon atoms and 1 to 3 nitrogen atoms and/or one oxygen or sulphur atom, and each of which is optionally substituted by halogen, C1-C4-alkyl or C1-C4-halogenoalkyl, to salts of the compounds of the formula (I), to processes for the preparation of these compounds, and to their use as herbicides. |
