A chitosan-supported imine palladacycle complex has been synthesized by salicylaldehyde via grafting on chitosan to form chitosan-Schiff base, followed by reacting with Li2PdCl4 in methanol. The catalyst has high activity and stereoselectivity for arylation of conjugate alkenes with aryl halides. This chitosan-supported imine palladium catalyst can be recovered and reused.
