Bis(NHC)-Palladium(II) Complex-Catalyzed Dioxygenation of Alkenes

Abstract

Bis(NHC)-Pd(II) complexes derived from 1,1′-binaphthyl-2,2′-diamine (BINAM) were successfully first used to catalyze the dioxygenation of alkenes under mild conditions tolerant of air and moisture. Cationic NHC-Pd2+ diaquo complex 1e showed the highest catalytic activity to give 1,2-dioxygenation products with good syn-diastereoselectivity for 1,2-disubstituted alkenes.
