Abstract

The invention relates to novel substituted sulphonylamino(thio)carbonyl compounds of the formula (I) ##STR1## in which PA1 A represents a single bond, represents oxygen, imino (NH), alkanediyl (alkylene) or alkylimino (N-alkyl), PA1 J represents a (hetero)aryl grouping selected from the series phenyl, pyridyl, pyrazolyl, thienyl which is substituted by a 5,6-dihydro-[1,4,2]-dioxazin-3-yl group (which may for its part be substituted by halogen, alkyl or halogenoalkyl) and optionally by one or two further radicals selected from the series cyano, halogeno, alkyl, halogenoalkyl, phenyl, pyridyl, PA1 Q represents oxygen or sulphur and, PA1 R represents optionally substituted heterocyclyl having 5 ring members of which at least one is oxygen, sulphur or nitrogen and one to three more may be nitrogen, and salts of compounds of the formula (I), processes and specific novel intermediates for their preparation and their use as herbicides.
