α,β-不饱和醛酮的选择性均相催化氢化
Selective Homogencous Catalytic Hydrogenation of α, β-Unsaturated Aldehydes and Ketones
【摘要】 <正> 可溶性的过渡金属络合物的均相催化氢化是一个被广泛研究的课题,通常,烯烃是氢化的底物,但其他基团,如炔、醛、酮、硝基和芳环等也同样能够被氢化。所以,在有机合成中,选择性催化氢化就显得更为重要。1965年Wilkinson催化剂的问世,给均相催
【Abstract】 A new complexe was generated in situ from 1,4-bis (diphenylphosphino)butane (1) and acetylacetonato-dicarbonyl rhodium (2). It is a highly selective homogeneous catalyst. In hydrogenation reaction, adjacent double bond of carbonyl is only reduced by this system. The hydrogenation was carried out at atmosphere and ambient temperature with the yield 70～100%.
