N-SUBSTITUTED HYDRAZINOPHENYLSULPHONYLUREAS, AS HERBICIDES AND PLANT GROWTH REGULATORS

摘要

Compounds of the formula (I) or salts thereof are suitable as herbicides and plant growth regulators. The compounds (I) are prepared by processes analogous to known processes, in some cases via novel intermediates of the formula (II) R5 represents H, halogen atoms, NO2, CN or optionally halogen substituted (C1-C4)alkyl, alkoxy, alkylcarbonyl or alkoxycarbonyl; R6 represents H or (C1-C4)alkyl; Q represents 0 or NR*; W represents O or S; Z represents CH or N; X and Y represent H, halogen atoms or optionally substituted (C1-C4) alkyl, alkoxy or alkylthio; and R11 to R4 represent H or a range of organic radicals.
