General procedure: Diphosphine ligand (2.0 mmol) was dissolved in 10 mL of dichloromethane and the solution was added dropwise to a stirred solution of RuCl2(PPh3)3 (1.0 mmol) in 10 mL of dichloromethane. The reaction mixture was stirred approximately for 50 min at room temperature. The brown solution was filtered to remove the insoluble impurities. The solvent was reduced by a vacuum and the product was then precipitated by adding n-hexane. The yellow solid was filtered and washed three times with 20 mL of diethyl ether.
