Abstract

A simple procedure for clean and economic synthesis of alkanesulfonyl chlorides via bleach-mediated oxidative chlorosulfonation of S-alkyl isothiourea salts is disclosed. This procedure is environment- and worker-friendly with the advantages of readily accessible materials and reagents, simple and safe operations, easy purification without chromatography, and affords high yields of up to 99%.
