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.
To a solution of ONS-LH (486mg, 2.0mmol) in THF (20mL) was added [Ru(PPh3)3Cl2] (868mg, 2.0mmol), which was then stirred under N2 for 15min. Triethylamine (Et3N) (202mg, 2.0mmol) was introduced, and the reaction mixture was stirred overnight at room temperature, during which the color of solution changed from brown to dark red brown. After removal of solvents in vacuo, CH2Cl2 (20mL) was added and the solution was filtered. The filtrate was concentrated and the residue was washed with Et2O (5mL¡Á2) and hexane (5mL¡Á2) to give the desired product. Recrystallization from MeOH/ Et2O (1:3) afforded dark red block crystals of 1¡¤0.5CH3OH¡¤2.75H2O suitable for X-ray diffraction in five days. Yield: 1.19g, 63% (based on Ru). IR (KBr disc, cm-1): 1597 (nuC=N), 1311 (nuC-O), 739 (nuC-S), 1432, 1087 and 691 (nuPPh3); 31P NMR (CDCl3, 162MHz): delta 16.4 (s, PPh3), 14.7 (s, PPh3) ppm. 1H NMR (CDCl3, 400MHz): delta 8.81 (s, 1H, CH=N), 7.98-7.31 (m, 4H, Ar-H), 7.23-7.06 (m, 4H, Ar-H), 6.75-7.01 (m, 30H, PPh3), 2.39 (s, 3H, SCH3) ppm. MS (FAB): m/z 903 [M+], 868 [M+-Cl], 641 [M+-PPh3], 379 [M+-2PPh3], 344 [Ru(ONS-L)]+. Anal. Calc. for C50H42NOP2ClSRu¡¤0.5(CH4O)¡¤2.75(H2O) (%): C, 64.74; H, 4.98; N, 1.48. Found: C, 64.67; H, 5.03; N, 1.43
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
