摘要

A highly efficient protocol for the Pd-catalyzed regioselective Heck arylation of the electron- rich olefin N-acyl-N-vinylamine with aryl halides has been developed. In the presence of hydrogen-bond donor [H2NiPr2][BF4] as an additive, this proceeds smoothly in isopropanol to afford exclusively the branched products in high yields.
