A simple NaClO2-mediated oxidative chlorosulfonation of S-alkyl isothiourea salts enables a convenient, safe, and environmentally benign synthesis of diverse sulfonyl chlorides in high yields. The procedure is also applicable to other substrates such as thiols, disulfides, thioacetates, and xanthates.
