Heck Reactions Catalyzed by Palladium Complex Supported on 4‐Aminopyridine Resin

Abstract

4-Aminopyridine resin-immobilized palladium catalyst was prepared by a simple procedure, which exhibited excellent activity at low loading levels for the phosphine-free Heck vinylation of activated and non-activated aryl or heteroaryl substrates with olefins in air. This method has the advantage of environmental benignity, generality, simplicity and potential for recycling of the resin catalyst.
