Application of Iodobenzene Acetate Promoted Oxidation in the Synthesis of 2-Amino-1,3,4-thiadiazole Molecules

Abstract

A highly method for intramolecular oxidative coupling reaction of thiosemicarbazone promoted by hypervalent iodine reagent was reported. 2-Amino-1,3,4-thiadiazole derivatives could be synthesized effectively. Hypervalent iodine could be used as a mild reagent with low toxicity, low cost, easy circulation and operation. The reaction had the advantages of easy preparation of raw materials, simple operation and better performance. The applicability of substrates and the reaction mechanism were also preliminarily studied.
