| 摘 要： | 配合物Ｒｕ（ＯＡｃ）２（Ｐｈ３Ｐ）２与不同摩尔比的双膦配体ｄｐｐｐ［ｄｐｐｐ＝双－（二苯基磷）丙烷］或ｄｐｐｂ［ｄｐｐｂ＝双－（二苯基膦）丁烷］在回流的甲苯中反应，分别生成资合双膦钌配合物Ｒｕ（ＯＡｃ）２（Ｐｈ３Ｐ）（ｄｐｐｐ）、Ｒｕ（ＯＡｃ）２（ｄｐｐｐ）２和Ｒｕ（ＯＡｃ）２（ｄｐｐｂ）。这些配合物经元素分析、熔点测定、红外光谱和核磁共振等手段进行了表征。在反应温度３０～６０℃，氢压为３．０ＭＰａ的条件下，发现题示配合物是均相催化丙烯酸和苯乙烯选择氢化的有效催化剂。

| Abstract: | nteraction of Ru (OAc)2(Ph3P)2 with 1 or 2 equivalent of bis-(diphenylphosphino) propane, i. e. dppp, or bis-(diphenylphosphino) butane, i. e. dppb, in refluxing toluene gives chelated diphosphine ruthenium (Ⅱ) complexes Ru (OAc)2(Ph3P) (dppp), Ru(OAc)2(dppp)2 and Ru (OAc)2(dppb), respectively.The complexes are characterized by elemental analysis, melting point testing, IR and NMR spectrometries. It is found that the complexes are effective catalysts for homogeneous hydrogenation of acrylic acid and styrene with methanol as a solvent under the reaction conditions of 30～60℃ and 3.0MPa hydrogen pressure. |
