Abstract

Abstract : A PPh3 modified-chitosan supported Pd nanocatalyst has been developed for heterogeneous Suzuki–Miyaura cross coupling reactions with high catalytic activity, wide substrate compatibility and good recyclability. 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.
