Abstract

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 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.

Key words: diphosphine ligand, ruthenium complex, acrylic acid, styrene, hydrogenation
