SUBSTITUTED SULPHONYLAMINO (THIO)CARBONYL COMPOUNDS AS HERBICIDES

摘要

The disclosure relates to novel substituted sulphonylamino (thio)carbonyl compounds of formula (I) in which: A stands for oxygen, sulphur, NH, N-alkyl, N-aryl, -CH=N- or -N=CH- or -CH=CH-; Q stands for oxygen or sulphur; R1 stands for (in each case optionally substituted) alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aryl, arylalkyl, heterocyclyl or heterocycloalkyl; R2 stands for cyano, nitro, halogen, or for (in each case optionally substituted) alkyl, alkoxy, alkoxycarbonyl, alkylthio, alkylsulphinyl, alkylsulphonyl, alkenyl, alkinyl, alkenyloxy or alkinyloxy; R3 stands for (in each case optionally substituted) heterocyclyl with 5 ring members, at least one of which can be oxygen, sulphur or nitrogen and one to three others can be nitrogen. Certain previously known individual compounds are excluded. Also disclosed are salts of novel compounds of formula (I), various processes and novel intermediate products for producing the novel compounds, and the use of these compounds as herbicides.
