abstract |
The invention concerns novel substituted thienyl(amino)sulphonyl(thio)ureas of formula (I), in which A stands for nitrogen or a CH group; E stands for a single bond or an NH group; Q stands for oxygen or sulphur; R<1> and R<2>, independently of each other, stand for hydrogen, halogen or in each case optionally substituted alkyl, alkoxy, alkylthio, alkylamino, dialkylamino, cycloalkyl, cycloalkyloxy, aryloxy or heterocyclyloxy; R<3> stands for hydrogen or optionally substituted alkyl; R<4> and R<5>, independently of each other, stand for cyano, halogen or in each case optionally substituted alkyl, alkoxy, alkenyl, alkenyloxy, alkinyl or alkinyloxy; and R<6> stands for hydrogen, cyano, halogen or in each case optionally substituted alkyl, alkoxy, alkenyl, alkenyloxy, alkinyl or alkinyloxy. The invention further concerns salts of compounds of formula (I), a process for preparing the novel compounds and their use as herbicides. |
