摘　　要：研究了一系列二苯基膦乙酰腙的 Pd( )配合物新催化剂在常压条件下催化烯烃加氢的性能 .发现 P、N二齿配位结构的催化剂显示出好的催化活性 ,配体苯环上的供电子基对催化有明显的促进作用 ;P、N。Catalytic activities of the palladium (Ⅱ) complexes for hydrogenation of olefins were studied. The effects of temperature, catalyst amount and solvents were investigated. The results indicate that the structure of the complexes influenced their catalytic activities. The experiments of 2b and 4b show that an oxide\|palladium bond was formed, which is in accordance with the results of XPS analysis. The hydrogenation of different olefins under the same reaction conditions were studied.
