A novel Cu-catalyzed direct hydrosulfonylation of alkynes with arylsulfinic acids for the synthesis of (E)-vinyl sulfones has been realized under mild conditions with 100% atom efficiency. The present protocol provides an attractive approach to various vinyl sulfones in good to excellent yields, with the advantages of operation simplicity, atom economy, and high stereo- and regioselectivities.
