Here we report the sulfinylsulfonation of alkynes to afford β-sulfinyl alkenylsulfone products with a broad substrate scope, excellent functional group compatibility, and high yield. Moreover, the sulfinylsulfonation reaction of enyne can also be realized for constructing functionalized carbo- and heterocycles through a radical cascade cyclization process.
Keywords: Alkynes; Sodium sulfinate; Sulfinylsulfonation Sulfones; β-Sulfinyl alkenylsulfone.
