Name is Dichlorotris(triphenylphosphino)ruthenium (II), as a common heterocyclic compound, it belongs to ruthenium-catalysts compound, and cas is 15529-49-4, its synthesis route is as follows.,15529-49-4
Into a solution of L1 (0.037 g, 0.09 mmol) in methanol (25 mL) the complex [RuCl2(PPh3)3] (0.07 g, 0.07 mmol) was added. The resulting solution was refluxed for 5 h under visible light (125 W halogen lamp), then cooled at room temperature and concentrated to 2 mL. The precipitate was obtained after the addition of 50 mL of diethyl ether/n-pentane (1:1) to the concentrated solution. The product was filtered, washed with diethyl ether/n-pentane (1:1) (2 * 25 mL) and dried in the vacuum. A solution of 1 in methanol was kept at room temperature for slow evaporation under daylight. Single crystals (light green) suitable for X-ray structure determination were obtained after one week. Yield: 0.49 g, 93%. Elemental analyses for RuC42H36Cl2N7P (841.72): calcd C 59.89, H 4.28, N 11.64%; found C 60.38, H 4.51, N 11.26.
