Herbicidal sulfonylureas
-
, (2008/06/13)
Substituted sulfonylureas of the general formula I STR1 where n and m are each 0 or 1, and R1 is hydrogen, alkyl, alkenyl or alkynyl; R2 is halogen or trifluoromethyl when m is 0, or, when m is 1, alkyl, alkenyl or alkynyl and, when X is 0 or S and m is 1, is trifluoromethyl or chlorodifluoromethyl; X is 0, S or N--R4, where R4 is hydrogen or alkyl; R3 is hydrogen, halogen, alkyl, haloalkyl or alkoxy; A is haloalkyl, halogen or STR2 where Z is oxygen or alkylimino N--R6 ; R5 is hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, alkenyl or alkynyl; R6 is hydrogen, alkyl, or together with R5 is a C4 -C6 -alkylene chain, where one methylene may be replaced by an oxygen atom or a C1 -C4 -alkylimino group, and R7 is hydrogen or halogen, and environmentally tolerated salts thereof, processes and intermediates for the manufacture of compounds I, and their use as herbicides and bioregulators.
