MCM-41-supported bidentate phosphine palladium(0) complex as an efficient catalyst for the heterogeneous Suzuki reaction

MCM-41-supported bidentate phosphine palladium(0) complex was conveniently synthesized from commercially available and cheap γ-aminopropyltriethoxysilane via immobilization on MCM-41, followed by reacting with diphenylphosphinomethanol and palladium chloride and then the reduction with hydrazine hydrate. The powder X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) were employed to characterize the title palladium complex. It was found that this complex is a highly active catalyst for the heterogeneous Suzuki reaction of aryl halides with arylboronic acids and can be reused many times without loss of activity.
