The invention relates to novel thienylsulphonylamino(thio)carbonyl compounds of the formula (I), in which Q represents oxygen or sulphur, R1 represents cyano, halogen or in each case optionally cyano-, halogen- or C1-C4-alkoxy-substituted alkyl, alkenyl, alkinyl, alkoxy, alkenyloxy or alkinyloxy having in each case up to 6 carbon atoms, R2 represents cyano, halogen or in each case optionally cyano-, halogen- or C1-C4-alkoxy-substituted alkyl, alkenyl, alkinyl, alkoxy, alkenyloxy or alkinyloxy having in each case up to 6 carbon atoms, and R3 represents in each case optionally substituted heterocyclyl having 5 ring members, at least one of which represents oxygen, sulphur or nitrogen and one to three others may represent nitrogen, and salts of compounds of the formula (I), to processes and novel intermediates for preparing the novel compounds and to their use as herbicides.
