摘要

(Het)Arylsulfonylureas having an imino function, their preparation, and their use as herbicides and plant growth regulators Compounds of the formula (I) and salts thereofin which A is a (hetero)aromatic or heterocyclic bridge linked to the group SO2 by a direct bond, or via O, S, NH, CH2 or via alkylated NH or alkylated methylene, B is a group having an imino-containing fragment N=C-N, N=C-S, N=C-O or N=C-C which is linked to A by one of the nitrogen atoms of the fragment, R=H or an aliphatic radical, W=O or S and X, Y and Z are as defined in claim 1 are suitable as herbicides and plant growth regulators. The preparation is carried out for example similarly to known processes via novel intermediates of the formula (XII) (cf. claims 6 and 10),
