Abstract

Abstract : A general visible light-promoted and electron–donor–acceptor complex-enabled cascade reaction of alkynes to produce functionalized sulfur-containing heterocycles under photocatalyst-, base-, oxidant- and metal-free conditions was developed. Abstract : We disclosed a general visible light-promoted and electron–donor–acceptor complex-enabled cascade reaction of alkynes via a radical addition/cyclization cascade sequence under photocatalyst-, base-, oxidant- and metal-free conditions. Arylsulfinic acids as electron donors and methylthio substituted aromatics as electron acceptors were applied to produce functionalized sulfur-containing heterocycles.
