A natural friendly iron-immobilized on imidazolium supported ionic liquid [Gmim]Cl-Fe (III) was effectively evaluated as a heterogeneous catalyst for Mizoroki-Heck reaction with good to excellent yield under solvent free condition. [Gmim]Cl-Fe (III) showed good activities that were comparable to that of palladium catalysts. Furthermore, this phosphine, copper and palladium- free catalyst was simply recovered from the reaction mixture and recycled seven times.
