Abstract

An efficient method has been described for the synthesis of vinyl sulfones via hydrosulfonylation of alkynes using sodium arene sulfinates catalyzed by Cu(OTf)2 under microwave irradiation. A variety of vinyl sulfones was obtained in good to excellent (71–89%) yields and with high regio- and stereoselectivity. Shortened reaction times, simple reaction conditions and low catalyst loading are the salient features of this protocol.
