Abstract

合成了双膦醋酸钌配合物,不同温度的1H NMR谱表明,两个醋酸根分别以单齿和双齿配体与中心钌(Ⅱ)配位;31P NMR和X-射线结构分析表明膦配体为面式构型.配合物对丙烯酸和苯乙烯有选择氢化活性.

Interacting Ru(OAc)2(Ph3P)with dppm(bis(diphenylphosphino)methane)in refluxing toluene gave Ru(OAc)2(Ph3P)(dppm) and Ru(OAc)2(dppm)2 in yields of 79% and 8l%, respectively.1H NMR study carried out at various temperatures showed that the two acetates are coordinated to the central Ru(Ⅱ) in forms of monodentate and didentate.31PNMR and X-ray diffractometric results revealed the fac-configuration of phosphine ligands.Under hydrogen pressures of 1.0~4.0MPa and temperatures 30~70℃, the title complexes showed a catalytic activity to the selective hydrogenation of acrylic acid and styrene.
