摘要
合成了两个新的胺膦钌配合物ｔｒａｎｓ－ＲｕＣｌ２（Ｐ２Ｎ２Ｍｅ）和ｔｒａｎｓ－ＲｕＣｌ２（Ｐ２Ｎ２Ｈ４Ｍｅ）．进行了元素分析、ＩＲ、ＮＭＲ等谱学或Ｘ射线衍射分析．它们均具有六配位八面体构型．在碱性介质中，以异丙醇为溶剂，两个配合物可作为有效的催化剂实现苯乙酮的氢转移还原．讨论了催化氢化机理．
Interaction of RuCl2(DMSO)4 with one equivalent of N,Nbis[o(diphenylphosphino)benzylidene]1,2propanediamine[P2N2Me] or N,Nbis[o(diphenylphosphino)benzyl]1,2propanediamine[P2N2H4Me] in refluxing toluene gave transRuCl2(P2N2Me) and transRuCl2(P2N2H4Me) in moderate yield, respectively. The complexes have been fully characterized by analytical and spectroscopic methods. The structure of transRuCl2(P2N2Me) has been established by an Xray diffraction study and the result indicates a distortedoctahedral configuration. The complexes were found to be an effective catalyst for hydrogen transfer hydrogenation of acetophenone. The catalytical cycle mechanism is also discussed.
