Reactions and Biological Activities of Hydrazonoyl Halides

Current Organic Synthesis
Abstract: This review covers the literature information on the chemistry of hydrazonoyl halides with different substrates to give heterocyclic compounds. From the foregoing survey, it seems this provides a useful and convenient strategy for the synthesis of numerous heterocyclic derivatives.

Hydrazonoyl Halides Precursors to Synthesis of New Thiazole, Thiadiazole, and Benzothiazepine Derivatives

Journal of Heterocyclic Chemistry, 2016
New series of substituted thiazole and thiadiazoles were prepared starting from N′‐(3,4‐dihydronaphthalen‐1(2H)‐ylidene)hydrazinecarbothiohydrazide by reacting with different types of hydrazonoyl chlorides. In addition, 7‐(4‐chlorophenyl)‐5,6,6a,7‐tetrahydrobenzo [b]naphtha‐[1,2‐e][1,4]thiazepine reacted with hydrazonoyl halides to afford a new ...
