Benzenesulfonyl hydrazide

A most widely used decomposable chemical blowing agent is azodicarbonamide. Its decomposition temperature and rate of evolution of gaseous components are greatly influenced by the stabilizers containing zinc. Lead and cadmium are considered moderate activators for, -oxybis benzenesulfonyl hydrazide (OBSH). OBSH can also be used as a blowing agent for PVC foams. [Pg.420]

A number of hydrazides have been prepared in comparable yields from their respective sulfonyl chlorides by the procedure above. These include -bromobenzenesulfonylhydrazide, p-chlorobenzenesulfonylhydrazide, p - methoxybenzenesulfonylhy-drazide, w-nitrobenzenesulfonylhydrazide, />-nitrobenzenesulfon-ylhydrazide, o-nitrobenzenesulfonylhydrazide, benzenesulfonyl-hydrazide, and methanesulfonylhydrazide. [Pg.95]

Surprisingly, arylhydrazones 88a-d, upon treatment with 1-benzenesulfonyl-hydrazide 89 in refluxing ethanol, afforded very good yields of pyrazol-3-ones 90a-d (85JIC54) (Scheme 25). 5-Aminopyrazol-3-(Mies have also been synthesized from /3-cyanoesters (Section II,A,2) and from /3-iminoesters (Section II,A,3). [Pg.92]

Since diimide exists as a transient intermediate and cannot be isolated under normal conditions, procedures for reduction by diimide necessarily involve generation of the reagent in situ1 1 11. Diimide can be generated by (i) oxidation of hydrazine, (ii) acid decomposition of azodicarboxylate salts and (iii) thermal or base-catalyzed decomposition of substituted benzenesulfonyl hydrazides. [Pg.1001]

Lempert et al,42 described the reaction of benzenesulfonyl hydrazide with pyrylium salts to give pyrazolins which on heating with perchloric acid are converted into 1-benzenesulfonylaminopyridinium salts. [Pg.218]
