Abstract
A clean and economic synthesis of alkanesulfonyl chlorides via bleach-mediated oxidative chlorosulfonation of S-alkyl isothiourea salts is simple, environment- and worker-friendly. The procedure uses readily accessible reagents, offers safe operations and easy purification without chromatography, and affords high yields.
