On August 29, 1980, Elliott, Arthur J.; Gibson, Martin S. published an article.Quality Control of 3-Nitro-4-chlorobenzenesulfonamide The title of the article was Hydrazides and thiohydrazides as sources of condensed oxadiazines and thiadiazines, including novel azo derivatives based on dithizone. And the article contained the following:
Condensation reactions of N’-phenylbenzohydrazide, N’-phenylbenzothiohydrazide, and dithizone with a variety of activated aromatic and heteroaromatic 1,2-dihalo and 1-halo-2-nitro compounds are described in which the hydrazide or thiohydrazide functions as a bidentate nucleophile. These reactions lead to derivatives of the 4H-1,3,4-benzoxadiazines e.g. I, and 4H-1,3,4-benzothiadiazines and analogous pyrimido-, pyrazino-, and quinoxalinooxadiazines and -thiadiazines, which are representative of new ring systems. The corresponding reaction of N’-phenylbenzothiohydrazide with chloranil proceeds with expulsion of S. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Quality Control of 3-Nitro-4-chlorobenzenesulfonamide
