Abstract

The N-benzylation of NH-sulfoximines via visible light photocatalysis is realized. Under mild reaction condition, photocatalyst promotes the direct cross coupling of NH-sulfoximines with benzyl bromide to form N-benzylation sulfoximines. Superbases which are usually used in reported coupling of NH-sulfoximines with alkyl halides are not needed in this work. This method is also suitable for the synthesis of N-allyl sulfoximines.
