Palladium(II)-Catalyzed Aerobic Dialkoxylation of Styrenes:  A Profound Influence of an <i>o</i>-Phenol

Abstract

We report a Pd(II)-catalyzed aerobic dialkoxylation of styrene derivatives that requires an o-phenol. Initial scope and preliminary mechanistic studies are presented in which the o-phenol is proposed to facilitate the formation of a quinone methide intermediate.
