A new method has been developed to prepare [(Ph3P) 3Ru(CO)(H)2] (1), an important homogeneous catalyst, directly from RuCl3·xH2O. Unlike previously reported procedures to make 1, the new method does not utilize toxic and hazardous materials such as formaldehyde and benzene and requires only a small excess of PPh3, while furnishing analytically and spectroscopically pure 1 in unprecedented >95% yield. The solvent (EtOH) is used in small quantities, thereby enabling scalability, as has been demonstrated by preparing >17 g of pure 1 in one batch.

reacts with excess triphenylphosphane in acetic acid to give fac-*2CH3COOH (1), which crystallizes in the triclinic space group with Z = 2.The three phosphane ligands are in the sterically congested facial configuration, and the distorted octahedral geometry around the metal is completed by a unidentate and chelating acetate.A variable temperature 31P(1H)-NMR study of the complex in CH2Cl2 showed the three phosphanes to be inequivalent at low temperature.On raising the temperature two separate coalescence processes are observed, ultimately making all of the phosphanes equivalent at room temperature.Complex 1 shows slight catalytic activity for the ring-opening polymerization of bicyclohept-2-ene (norbornene).Key Words: fac-*2CH3COOH / Tris(triphenylphosphane)ruthenium(II) / Polymerization / Bicyclohept-2-ene / Ruthenium complexes
