Hydrazinosulfonylation of aryl electrophiles: a straightforward approach for the synthesis of aryl N-aminosulfonamides

Abstract

In recent years, the direct hydrazinosulfonylation of aryl electrophiles with SO₂ and hydrazines has emerged as an efficient and versatile method for the synthesis of aryl N-aminosulfonamides. This method has the advantages of being operationally simple and requiring only readily available starting materials. This review article is an attempt to survey literature describing the preparation of aryl N-aminosulfonamides through the direct hydrazinosulfonylation of aryl electrophiles with SO₂ and hydrazines, with special attention paid to the mechanistic features of the reactions. It can be used as a guide for chemists to apply the best hydrazinosulfonylation conditions in their work or serve as inspiration for future research related to the topic.
