摘要: 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 palladium chloride then the reduction hydrazine hydrate. The powder X-ray diffraction (XRD) photoelectron spectroscopy (XPS) were employed to characterize title complex. It found that this is a highly active catalyst for heterogeneous Suzuki reaction of aryl halides arylboronic acids can be reused many times without loss activity.
