ALKYLIDENEHYDRAZINOPHENYLSULFONYLUREAS, PROCESSES FOR THEIR PREPARATION AND THEIR USE AS HERBICIDES AND PLANT GROWTH REGULATORS

摘要

Alkylidenehydrazinophenylsulfonylureas, processes for their preparation and their use as herbicides and plant growth regulators Compounds of the formula (I) and salts thereof (see formula I) in which R1 to R6, W, X, Y and Z are defined as in claim 1, have herbicidal or plant growth-regulatory properties. They can be prepared by processes analogous to known processes (cf. claim 5), in some cases via novel intermediate products (cf. formula II): (see formula II)
