Allylic Carbon-Carbon Double Bond Directed Pd-Catalyzed Oxidative ortho-Olefination of Arenes
Pd-catalyzed selective ortho-olefination of arenes assisted by an allylic C-C double bond at room temperature using O-2 as a terminal oxidant is described. A possible mechanism involving the initial coordination of allylic C=C bond to Pd followed by selective o-C-H bond metalation is proposed.
