Sulphonhydrazides and related compounds. Part VI. Some halogeno- and nitro-benzenesulphonhydrazides

Abstract

4-Chloro-3-nitro-, 4-hydrazino-3-nitro-, o- and m-nitro-, p-bromo-, 2,4-, 2,5-, and 3,4-dichloro-, also 2,3,4- 2,4,5-, and 2,4,6-trichloro-benzenesulphonhydrazides have been prepared and converted into a number of derivatives (e.g., hydrazones, azides) required as potential pest-control agents. The relative stability of the various sulphonyl hydrazides is briefly discussed.
