An efficient and convenient copper catalyst system for the solvent-free Heck reaction

Abstract

A novel 1-glycyl-3-methyl imidazolium chloride-copper(II) complex [[Gmim]Cl–Cu(II)] was found to be a heterogeneous catalyst for an efficient Heck reaction with good to excellent yield under solvent free condition. This protocol provides a simple strategy for the generation of a variety of new C–C bonds under environmentally benign condition. The catalyst was reused up to nine consecutive cycles without any significance loss in its activity.
