Abstract

A PPh₃ modified-chitosan support was synthesized by the acid-mediated addition reaction of the tris(4-vinylphenyl)phosphane ligand (3vPPh₃) and chitosan (CS). The material was loaded with Pd(OAc)₂ to furnish a supported Pd catalyst (Pd/PPh₃-CS), which was characterized by FT-IR, ICP-MS, TGA, XPS, SEM, TEM and N₂ adsorption–desorption analysis. The catalyst showed a high catalytic activity, wide substrate compatibility and good recyclability in heterogeneous Suzuki–Miyaura cross coupling reactions.
