Synthesis and Catalytic Activity of Ru(OAc)2(Ph3P)(dppm) and Ru(OAc)2(dppm)2
Abstract:
Interacting Ru(OAc)2(Ph3P) with dppm (bis(diphenylphosphino)methane) in re-fluxing 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. 31P NMR 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.
