Allylic Carbon–Carbon Double Bond Directed Pd-Catalyzed Oxidative <i>ortho</i>-Olefination of Arenes

Abstract

Pd-catalyzed selective <i>ortho</i>-olefination of arenes assisted by an allylic C–C double bond at room temperature using O₂ as a terminal oxidant is described. A possible mechanism involving the initial coordination of allylic CC bond to Pd followed by selective <i>o</i>-C–H bond metalation is proposed
