A Remarkable Improvement of Catalytic Performance by Electronic Substituent Effects of Chiral P-N Hybrid Ligands in Palladium-Mediated Asymmetric Allylations

Abstract
A marked advancement of reactivity and enantioselectivity in palladium-catalyzed asymmetric allylations was achieved by variations of electronic substituent effects in a new series of chiral P-N hybrid ligands 1. The first evident observation demonstrates that the introduction of electron-donating groups is effective to improve the catalytic performance in the allylic transformation.
