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.
c) Preparation of the Complex Dichloro bis[3-(Diphenylphosphino)-1-propylamine]Ruthenium; ([RuCl2(L-2)2]). Under argon, a round-bottomed Schlenck flask, equipped with a magnetic stirring bar, was charged with RuCl2(PPh3)3 (1.028 g, 1.07 mmol) and with a solution of 3-(diphenylphosphino)-1-propylamine (566.8 mg, 2.33 mmol) in toluene (5 mL). More toluene (5 mL) was added to rinse. Then the dark-brown solution was heated in an oil bath at 100 C. for 16 h. The resulting brick-orange suspension was cooled to room temperature, and added to pentane (50 mL) with stirring. The yellow solid was collected by filtration, washed with pentane (2¡Á3 mL) and dried in vacuo to provide the desired complex (672.6 mg, 1.02 mmol, 95%) as a yellow-mustard solid. 31P{1H}-NMR analysis showed the presence of two species. 1H-NMR (CD2Cl2): delta (A) 7.19 (t, J=7.2 Hz, 4H), 7.14 (m, 8H), 7.05 (t, J=7.2 Hz, 8H), 3.28 (brs, 4H), 3.02 (brs, 4H), 2.66 (m, 4H), 2.0 (m, 4H). 13C-NMR (CD2Cl2): delta (A) 138.4 (t, J=19.2 Hz, Carom), 134.2 (t, J=4.8 Hz, CHarom), 129.0 (CHarom), 127.5 (t, J=4.8 Hz, CHarom), 41.3 (CH2), 26.9 (t, J=13.6 Hz, CH2), 24.7 (CH2). 31P{1H}-NMR (CD2Cl2): A (82%) delta=33.5 ppm (s), B (18%) delta=49.8 ppm (s).
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
