Abstract
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 81%, 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.
