Abstract

meso-2, 4-Bis (diphenylphosphino) pentane (m BDPP) has proved to be an effective regiocontrolling ligand for palladium-catalyzed internal arylation by aryl bromides of electron- rich olefins in a common solvent DMSO with no need for any halide scavengers. The arylation of the benchmark electron-rich olefin butyl vinyl ether took place smoothly to afford exclusively α-arylated product with high isolated yields. The better performance of m ...
