General procedure: To a round-bottomed flask with a stir bar was placed with [Ru(PPh3)3Cl2] (868 mg, 2.0 mmol) under the nitrogen. Pre-dried THF(10 mL) was added and the resulting mixture was stirred at room temperature. Then salen-enH2 (536 mg, 2.0 mmol) and a little excess of Et3N (252 mg, 2.5 mmol) in THF (5 mL) were added. The reaction mixture was stirred at room temperature overnight. After removal of solvents, CH2Cl2 (15 mL) was added and the solution was filtered through cilite. The filtrate was concentrated and the residue was washed with Et2O (5mL 2) and hexane (5 mL 2) to give the desired product. Recrystallization from CH2Cl2/Et2O (1:2) afforded green block-shaped crystals of [RuCl(PPh3)(salen)] (3) suitable for X-ray diffraction in three days. Yield: 1011 mg, 76% (based on Ru).

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.

RuCl2(PPh3)3 (1 g, 1 .04 mmol) and the ligand of formula (IVg) (obtained from Example 1 ) (231 .4 mg, 1 .1 mmol) were placed in a 25 mL Schlenk tube under argon atmosphere, and dissolved in dry diglyme (2 mL). The reaction mixture was heated to 165C for 2 h, allowed to cool down to room temperature and stored at -18C to precipitate further overnight. Cold Et2O (2 mL) was added while cooling with a dry ice//so-propa- nol bath. The precipitate was filtrated by cannula, and washed with Et2O (5 times 2 mL). The orange powder was dried in vacuo, affording 530 mg (79%) of Ru(6-MeNN- SEt)(PP i3)Cl2 as an orange powder. An equilibrium of two conformations of Ru(6- MeNNSEt)(PPh3)Cl2 are existent in solution, delivering a doubled set of signals in NMR.
