SULPHUR-SUBSTITUTED PHENYLSULPHONYLUREAS; PROCESSES FOR THEIR PREPARATION AND THEIR USE AS HERBICIDES AND PLANT GROWTH REGULATORS

摘要

Compounds of formula (I) and their salts in which R*, R1, R2, R3, X, Y, Z, W, n and m are as defined in claim 1 and especially R* is a formyl equivalent of the formula CHO, -CH=NR or CH(X1R')(X2R'') are suitable as herbicides and plant growth regulators. They are produced by prior-art like methods, partially with the use of novel intermediate products of the formula (XVII) in which R* = NH2, Cl, (substituted) amino.
