| abstract |
The invention relates to novel substituted arylsulphonyl(thio)ureas (see formula I) in which A ~represents nitrogen or a CH grouping, Q ~represents oxygen or sulphur, R1 ~represents hydrogen, halogen or respectively optionally substituted alkyl, alkoxy, alkylthio, alkylamino, dialkylamino, cycloalkyl, cycloalkyloxy or hetero-cyclyloxy, R2 ~represents hydrogen, halogen or respectively optionally substituted alkyl, alkoxy, alkylthio, alkylamino, dialkylamino, cycloalkyl, cycloalkyloxy or hetero-cyclyloxy, R3 ~represents hydrogen or optionally substituted alkyl, R4 ~represents respectively optionally substituted alkyl, alkoxy, alkenyl, alkinyl, alkenyloxy, alkinyloxy, cycloalkyl, cycloalkyloxy or cycloalkylalkyl, and R5 ~represents hydrogen, formyl or respectively optionally substituted alkyl, alkyl-carbonyl, alkoxycarbonyl, alkylsulphonyl, alkenyl, alkinyl, cycloalkyl, cyclo-alkylcarbonyl, cycloalkylsulphonyl or heterocyclyl, and to salts of compounds of the formula (I), except for the compound N-(4,6-dimethyl-pyrimidin-2-yl)-N'-[2-(1,1,2,2-tetrafluoro-ethoxy)-6-methyl-phenylsulphonyl]-urea, to processes for preparing the novel compounds and to their use as herbicides. |
