摘　　要：我们曾研究了Cp2′TiCl2-PriMgBr体系存在下,二苯乙炔的催化加氢反应,为了探讨催化剂结构对反应的影响,本文考察了几种双核钛络合物的催化活性,发现它们能对炔烃的加氢起催化作用,随络合物分子中2个钛原子的靠近,其加氢催化活性明显减小。In this paper, we have investigated the catalytic action of a few binuclear Ti-H complexes on the hydrogenation of diphenyl ethyne in order to study the effects of the structures of the catalysts. It was found that the binuclear Ti-H complexes can also catalyze the hydrogenation of diphenyl ethyne. The catalytic action of binuclear Ti-H complexes is similar to that of the mononuclear ones and relates to their structures.
