Stereoselective synthesis of α-chloro-sulphoxides from sulphoxides or sulphides and iodobenzene dichloride
Abstract
α-Chlorination of dialkyl and aryl alkyl sulphoxides by iodobenzene dichloride is highly stereospecific, and in benzyl methyl sulphoxide involves the proton diastereotopic to that which is preferentially exchanged by deuterium in NaOD–D2O.
