Re(CO)5Cl (0.10 g, 0.27 mmol) and suitable Ln ligand (0.27 mmol) were dissolved in argon-saturated acetonitrile (20 mL). The resulting solution was placed in 25 mL teflon lined hydrothermal synthesis autoclave reactor and heated to 150 C. The reaction was stopped after 20 h and the autoclave was gradually cooled to room temperature for 30 h. The resulting yellow (1, 4, 7) or orange (2, 3, 5, 6, 8, 9) solid was collected by filtration, washed with diethyl ether and dried.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1662-01-7,4,7-Diphenyl-1,10-phenanthroline,as a common compound, the synthetic route is as follows.

General procedure: The preparation of the homologous series of osmium complexes with alpha diimineligands was modified from previous literature methods [5]. The precursor Os(L)2Cl2 was synthesized by refluxing ammonium hexachloroosmate in a 1:2 M ratio with L = 2,2?-bipyridine (bpy), 1,10-phenanthroline (phen), or bathophenanthroline (dpp) in 10 mL of ethylene glycol under nitrogen for 45 min. After cooling to room temperature, sodiumhydrosulfite (0.17 M) was added to reduce the osmium from Os(IV) to Os(II). Precipitation of Os(bpy)2Cl2,Os(phen)2Cl2, and Os(dpp)2Cl2 was achieved via an ice-bath,and the solid was washed with deionized water and ethylether. Yields were close to 80 %.

The reaction mass was stirred at the same temperature for about 30 minutes and then allowed to warm to room temperature. After 1 hour, to the resulting reaction mixture was added slowly a solution of tetrabutylammonium acetate (0.359 g, 0.0019 mol) in dichloromethane (2 ml) under stirring. After 1 hour, the solvent from the reaction mixture was evaporated under reduced pressure to yield an oily residue. The oily mass was co-evaporated with xylene (2x10ml) to obtain a thick mass. This mass was partitioned between dichloromethane (10 ml) and water (10 ml). The combined organic extracts were washed with water (3xl0ml) and dried over anhydrous sodium sulphate.The solvent was evaporated under reduced pressure and the resulting oily mass was triturated with ether (3×10 ml), each time the ether layer was decanted and finally the residue was concentrated under reduced pressure to obtain 0.260 g of the titled product as white foam in 35% yield.Analysis:Mass: 490.4 (M-l) as free acid; for Molecular Weight: 732.9, Molecular Formula: C34H64N6O9S .

The product was purified by chromatography (SiO2, CH3CN:H2O:saturated aqueous KNO3 14:1.2:0.5). Addition of excess aqueous saturated KPF6 solution and removal of CH3CN under reduced pressure gave a red precipitate which was collected on Celite, washed with H2O (5 mL), EtOH (2 mL), Et2O (5 mL) and dissolved in CH3CN. Removal of solvent gave [Ru(1)(3)](PF6)2 as a red solid (74 mg, 68 mumol, 40%)., 112881-51-3
