With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.15529-49-4,Dichlorotris(triphenylphosphino)ruthenium (II),as a common compound, the synthetic route is as follows.
Wilkinson prepared cis-RuCl2(PPh3)2(NCPh)2 by the reaction of RuCl2(PPh3)3 with NCPh in acetone and characterized it by elemental analysis and infrared spectroscopy [1]. In our hands this compound can also be obtained by the reaction in toluene. A 0.099 g (0.10 mmol) sample of RuCl2(PPh3)3 was added to 0.032 mL (0.033 g, 0.32 mmol) of NCPh in 2 mL toluene. The resulting mixture was stirred rapidly for several seconds and immediately filtered. After 3-6 h at room temperature yellow crystals began to form. After about 24 h the supernatant was removed and the yellow crystalline RuCl2(PPh3)2(NCPh)2 was dried under vacuum to yield 0.093 g (0.10 mmol, 100%) of RuCl2(PPh3)2(C7H5N)2, m.p. = 186.5-187.9 C (dec), IR(KBr (cm-1): 3052 m, 2240 m, 2230 m, 2216 m, 1431 s, 1259 w, 1085 m, 1023 w, 740 s, 692 s, 512. 31P NMR (CDCl3): 25.6 s. X-ray quality crystals were obtained from a similar reaction that took place in an NMR tube in d-toluene.
