Using the natural polymer-chitosan as supporter, yellow powder of chitosan-immobilized palladium(II) chloride which was prepared bytreating chitosan with palladium chloride in ethanol at room temperature was refluxed in ethanol to produce chitosan-immobilized palladium(0) catalyst. Its catalytic performance for Heck arylation of acrylic acid with iodobenzene shows that the catalyst has high catalytic activity and regioselectivity for the synthesis of trans-phenylacrylic acid. The catalyst can be recovered by filtrationand washing with solvent, and reused for many times. The Heck arylation reactions of other substrates catalyzed by chitosan-immobilized palladium(0) complex were also investigated.

Key words: chitosan, palladium complex, trans-phenylacrylic acid, Heck arylation reaction
