Pd-Catalyzed Stereoselective Carboperfluoroalkylation of Alkynes

Abstract

A Pd-catalyzed three component reaction involving terminal alkynes, boronic acids, and perfluoroalkyl iodides is presented here. Trisubstituted perfluoroalkenes can be obtained in a highly regio- and stereocontrolled manner by the simultaneous addition of both aryl and CnFm groups across the triple bond in a radical-mediated process. The reaction is operationally simple offering a broad scope and functional group tolerance.
