2116247 9305048 PCTABS00020 Substituted sulphonyl ureas have the general formula (I), in which n and m equal 0 or 1 and the substituents have the following meaning: R1 is hydrogen, alkyl, alkenyl or alkinyl; R2 is halogen or trifluoromethyl, when m equals 0 or, when m equals 1, R2 is alkyl, alkenyl or alkinyl, and when X stands for O or S and m equals 1, trifluoromethyl or chlorodifluoromethyl; X is O, S or N-R4, whereas R4 is hydrogen or alkyl; R3 is hydrogen, halogen, alkyl, halogenalkyl, alkoxy or halogenalkoxy; A is NO2, NH2, OH, CN, SCN, S(O)oR5, SO2NR6R7, ER7, whereas E stands for O, S or NR9, the groups (a), (b) possibly substituted C1-C4-alkyl or C2-C4-alkenyl; R5 is a possibly substituted alkyl group, a possibly substituted cycloalkyl group, an alkenyl group or an alkinyl group; R6 is hydrogen, an alkoxy group, an alkyl group, or represents together with R7 a C4-C6-alkylene chain, wherein a methylene group may be substituted by an oxygen atom or a C1-C4-alkylimino group; R7 is a possibly substituted alkyl, alkenyl or alkinyl group, a cycloalkyl group and may also represent, when E = NR9, methyl sulphone, trifluoromethyl sulphone, ethylsulphone, possibly halogen-substituted acetyl, dimethylcarbamoyl, dimethylsulphamoyl; o equals 0, 1 or 2; p, q equal 0 and/or 1 (when p = 0, q = 0); R8 is hydrogen or halogen; R9 is hydrogen, methyl, ethyl; R10 is alkyl, halogenalkyl, alkoxyalkyl, alkenyl, cycloalkyl, halogenalkenyl or, when p = 1 and q = 0, it may also be alkylamino or dialkylamino. Also disclosed are their environmentally compatible salts, a process and intermediates for producing the compounds having the formula (I) and their use as herbicides.
