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.
A mixture of HL1 (80mg, 0.20mmol), triethylamine (20mg, 0.20mmol) and 1[Ru(PPh3)3Cl2] (192mg, 0.20mmol) were stirred in tetrahydrofuran (20mL) for 6h at room temperature, during which the color of solution changed from brown to dark red. After removal of solvents in vacuo, dichloromethane (20mL) was added and the solution was filtered. The filtrate was concentrated and the residue was washed with diethyl ether (5mL¡Á2) and hexane (5mL¡Á2) to give the desired product. Recrystallization from dichloromethane/hexane (1:3) afforded dark red block crystals of [Ru(L1)(PPh3)2Cl] (1) suitable for X-ray diffraction in three days. Yield: 140mg, 66% (based on ruthenium). IR (KBr disc, cm-1): nuC=N 1568 (m), nuC-O 1304 (s), nuC-S 744 (w), nuPPh3 1433(m), 1091(s) and 694 (w), nuC-Br 564 and 529 (s); 31P NMR (CDCl3, 162MHz): delta 17.0 (s, PPh3) ppm. 1H NMR (CDCl3, 400MHz): delta 9.82 (s, 1H, CH=N), 7.91-7.52 (m, 30H, PPh3), 7.21-7.10 (m, 2H, Ar-H), 6.35-6.20 (m, 4H, Ar-H), 2.17 (s, 3H, SCH3) ppm. MS (FAB): m/z 1061 [M+], 1026 [M+-Cl], 799 [M+-PPh3], 537 [M+-2PPh3], 513 [Ru(L1)]+. Anal. Calc. for C50H40NOP2ClBr2SRu: C, 56.59; H, 3.80; N, 1.32%. Found: C, 56.54; H, 3.83; N, 1.36%.
The chemical industry reduces the impact on the environment during synthesis,15529-49-4,Dichlorotris(triphenylphosphino)ruthenium (II),I believe this compound will play a more active role in future production and life.
