Palladium complexes of triaryl phosphine-functionalized imidazolium salts were successfully applied in the palladium-catalyzed Heck reaction. A highly efficient system is described for the coupling of a wide array of aryl bromides and iodides with acrylates and styrene derivatives in excellent yield.
