摘要
对既含有CC键又含有CO键的分子,CC键的选择加氢意义重大[1].α,β不饱和醛选择加氢成饱和醛就属于此类.钯是已知的可在温和条件下将α,β不饱和醛选择加氢生成饱和醛最有效的催化剂之一.人们曾研究了不同钯化合物催化剂对α,β不饱和醛中CC的双键选择加...
The bimetallic catalysts, PdCl 2 0.5 MY PPh 3 MY=NiCl 2, Ni(OAc) 2, Fe(acac) 3 , Co(OAc) 2, Co(acac) 2 or CoCl 2 reduced by NaBH 4, 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. A strong synergic effect occurs between Pd and the second metal component for the high selectivity. Among these catalysts, PdCl 2 0 5Co(OAc) 2 PPh 3 reduced by NaBH 4 is the best catalyst.
