Abstract

A facile copper(II)-catalyzed regio- and stereocontrolled synthesis of vinyl sulfones from terminal alkynes and arylsulfonyl hydrazides is described. Depending on the source of copper(II), two different kinds of vinyl sulfones, (E)-vinyl sulfones and (Z)-β-chlorovinyl sulfones were obtained and the addition of cyclohexanone played an important role in the reaction. These reactions display excellent chemoselectivity as well as stereoselectivity.
