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。

Abstract: Interaction of RuCl2(DMSO)4 with one equivalent of N,N’-bis[o-(diphenylpho-sphino)benzylidene]-1,2-propanediamine[P2N2Me] or N,N’-bis[o-(diphenylphosphino)benzyl]-1,2-propanediamine[P2N2H4Me] in refluxing toluene gave trans-RuCl2(P2N2Me)and trans RuCl2(P2N2H4Me)in moderate yield, respectively. The complexes have been fully cha racterized by analytical and spectroscopic methods. The structure of trans-RuCl2(P2N2Me)has been established by an X-ray diffraction study and the result indicates a distorted octahedral configuration. The complexes were found to be an effective catalyst for hydrogen transfer hydrogenation of acetophenone. The catalytical cycle mechanism is also discussed.
