A three-component Pd-catalyzed difunctionalization of internal and terminal alkynes with iodoperfluoroalkanes and boronic acids is reported here. Under low catalyst loading and mild reaction conditions, perfluoroalkylated tri- and tetrasubstituted olefins were obtained in very good yields and in excellent regio- and stereoselectivities.
