15529-49-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Dichlorotris(triphenylphosphino)ruthenium (II), cas is 15529-49-4,the ruthenium-catalysts compound, it is a common compound, a new synthetic route is introduced below.
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. MS, (FAB, m/z): 806 [M+, RuC42H36ClN7P], 56 (100%) [NC3H6], 508 [Ru C24H21N7]+, 544 [RuC24H21N7Cl]+, 770 [RuC42H36N7P]+. 1H NMR (CD3OD): delta 3.98, 4.54 (AB system, 2JHH = 15.0 Hz, N-CH2-bzimtrans-bzim, 2H+2H), 4.40 (s, N-CH2-bzimtransPPh3, 2H), 7.05-9.64 (m, aromatic, 27H). 13C{1H} NMR (CD3OD): delta 64.10 (s, N-CH2-bzimtransPPh3), 63.50 (s, N-CH2-bzimtrans-Cl), 110.6-123.4 (m, bzim-ring), 127.2-133.8 (aromatics). 31P{1H} NMR (CD3OD): delta 48.26 (s, PPh3). UV-Vis (H2O): nm [epsilon (dm3 mol-1 cm-1)]: 382 (1660). Cyclic voltammetry (CH3CN, 22 C): Eox = 0.87 mV; Ered = 0.81 mV; E1/2 = 0.84 mV.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Dichlorotris(triphenylphosphino)ruthenium (II), 15529-49-4
