摘要： RuCl2(Ph3P)4或RuCl2(DMSO)4在甲苯中直接与等摩尔的亚胺膦配体N,N'-双-[邻-(二苯基膦苯亚甲基)]乙二胺(P2N2)在甲苯中回流反应,高产率地合成了反式配位的双亚胺双膦钌配合物trans-RuCl2P2N2.在温和条件下,该配合物作为新型催化剂有效地催化α,β-不饱和酸和几种功能团烯烃的选择加氢反应。讨论了可能的催化活性物种。

Abstract: The trans form of the title complex was synthesized in high yield by interaction of equimole RuCl2(Ph3P)4 or RuCl2(DMSO)4(DMSO=dimethylsulfoxide)with P2N2(i.e.= N,N'-bis[o-(diphenylphosphine benzylidene)]ethylene diamine)in refluxing toluene. The complex has been investigated as catalyst for selective hydrogenation of α,β-unsaturated acids and some functionalized olefins. The hydrogenation catalytic activity was observed as follows: styrene>acrylic acid>benzaldehyde>salicyl aldehyde>cyclohexanone>furfural>methylacrylic acidacetophenone. The effect of addition of NH4PF6 or AgNO3 as promotor has also been studied.

Key words: diiminodiphosphine ligand, ruthenium complex, synthesis, hydrogenation, catalytic activity
