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.

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.

15529-49-4, Compound 5 (300.0 mg, 0.68 mmol) and degassed morpholine (10 mL) were placed in a 100-mL Young-Schlenk container substituted with argon gas. Thereafter, the Young-Schlenk container was placed in an oil bath, and heated to 120 C. while stirring the components in the Young-Schlenk container, thereby causing a reaction. The progress of the reaction was confirmed by thin-layer chromatography (TLC), and the heating was stopped after two hours. Subsequently, the morpholine in the reaction mixture restored to room temperature (25 C.) was removed after collection with a liquid nitrogen trap under reduced pressure (0.1 to 2 mmHg). At this time, the reaction mixture was sufficiently stirred, and the Young-Schlenk container was immersed in water at room temperature (25 C.) to prevent cooling of the Young-Schlenk container by the heat of vaporization. After sufficiently removing the morpholine, dichlorotris(triphenylphosphino)ruthenium (II) (648.6 mg, 0.68 mmol) and dehydrated toluene (15 mL) were added while introducing argon gas into the container, and the mixture was heated to 110 C. using an oil bath, thereby causing a reaction. The heating was stopped after two hours, and the reaction mixture was restored to room temperature (25 C.). Subsequently, dehydrated hexane (40 mL) was added to the reaction mixture in an argon gas atmosphere. Thereafter, the whole mixture, including the hexane layer and the toluene layer, in the Young-Schlenk container was stirred and completely mixed. After leaving the mixture unattended for an hour, the generated purple substance was filtered out in an argon atmosphere while being washed with dehydrated diethylether, thereby obtaining a crude product. Subsequently, the resulting crude product was subjected to column chromatography (developing solvent: chloroform/ethyl acetate=5/1) in which silica gels are accumulated to about 10 cm, thereby removing a compound with high polarity. The effluent was collected to a flask and the collection was continued until the color of the purple liquid was slightly diluted. After this operation, the solution collected in the recovery flask was rapidly concentrated by an evaporator, thereby obtaining 204.3 mg (0.35 mmol, 51%)of substantially pure Compound 2b (RUPIP2) as a purple substance. The spectral data of Compound 2b (RUPIP2) is shown below. 1H NMR (600 MHz, CDCl3): delta 7.89 (d, 2H, J=8.3 Hz, C10H6N2), 7.69 (t, 2H, J=7.6 Hz, C10H6N2), 7.59 (d, 2H, J=8.3 Hz, C10H6N2), 3.89 (d, 4H, J=7.6 Hz, PCH2), 2.67-2.78 (m, 4H, CH(CH3)2), 1.35-1.43 (m, 24H, CH(CH3)2). 13C NMR (151 MHz, CDCl3): delta 163.3, 158.3, 134.4, 121.9, 120.0, 42.1 (d, 1JPC=20.2 Hz), 25.4, 20.5, 19.4. 31P{1H} NMR (243 MHz, CDCl3): delta 60.6.
