文摘

A copper-catalyzed highly regio- and stereospecific selenosulfonation of alkynes with arylsulfonohydrazides and diphenyl diselenide has been developed. This novel three component reaction proceeds under very mild conditions and with a broad scope of substrates, providing a wide range of (E)-β-selenovinyl sulfones in good to excellent yields.
