Abstract: The bimetallic catalysts, PdCl20.5 MY-PPh3 MY=NiCl2, Ni(OAc)2, Fe(acac)3, Co(OAc)2, Co(acac)2 or CoCl2 reduced by NaBH4, exhibit much higher selectivity in comparison with that of the monometallic Pa catalyst in the selective hydrogenation of cinnamaldehyde to 3-phenylpropanal at 66 ℃ under atmospheric pressure. Astrong synergic effect occurs between Pd and the second metal component for the high selectivity. Among these catalysts, PdCl2-0.5Co(OAc)2-PPh3 reduced by NaBH4 is the best catalyst.

Key words: Selective hydrogenation, Bimetallic catalysts, 3-Phenylpropanal, Cinnamaldehyde
