The coupling reactions of phenols and nitrogen hetereocycles with aryl halide were catalyzed by a highly active, readily available and easily recoverable heterogeneous Cu catalyst which was prepared by simply stirring an suspension of chitosan in solvent with copper compound. The result showed that chitosan@Cu2O catalyst catalyzed the coupling reactions of aryl halides with phenols and nitrogen hetereocycles to readily give the corresponding products in moderate to excellent yields. The highly active catalyst can be reused many times without losing its catalytic activity.

Key words: chitosan@Cu catalyst, synthesize, catalyze, Cross-coupling
