Metal- and base-free reductive coupling reaction of P(O)–H with aryl/alkyl sulfonyl chlorides: a novel protocol for the construction of P–S–C bonds

Abstract

Novel and efficient synthesis of S-aryl/alkyl phosphinothioates from P(O)–H and aryl/alkyl sulfonyl chlorides under metal- and base-free conditions is described. This reaction provides an alternative strategy for the construction of P–S–C bonds in moderate to excellent yields. Moreover, this method can be readily applied to gram-scale preparation.
