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.

Compound 10 (628.5 mg, 1.0 mmol) and degassed morpholine (15 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 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. (0255) After sufficiently removing the morpholine, dichlorotris(triphenylphosphino)ruthenium (II) (958.8 mg, 1.0 mmol) and dehydrated toluene (20 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.). (0256) 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. (0257) Subsequently, the resulting crude product was subjected to column chromatography (developing solvent: chloroform/THF=10/1) in which silica gels were 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 563.7 mg (0.73 mmol, 73%) of substantially pure Compound 2f (RUPCY3) as a purple substance.

EXAMPLE 1 Metathesis by Ethenolysis of Methyl Oleate Catalyzed by a Type 3 Complex (FIG. 1) in an Ionic Liquid; 1 ml of 3-butyl-1,2-dimethylimidazolium bis-triflylamide with formula [BMMI]+[N(CF3SO2)2]- pre-dried overnight at 80 C., 148 mg of methyl oleate (source: Fluka, with a purity higher than 98%) and 15 mg of the complex with formula Cl2Ru(CH-o-O-iPrC6H4)PCy3 (synthesized by reacting the 1st generation Grubbs complex with formula Cl2Ru(CHC6H5)(PCy3)2 with 1-isopropoxy-2-vinylbenzene in the presence of CuCl), this corresponding to 5% molar of catalyst with respect to methyl oleate, were introduced, in an inert atmosphere of argon, into an autoclave reactor provided with an agitation system and a pressure sensor. The autoclave was then placed under vacuum and pressurized to obtain a pressure of 10 bars (1 MPa) of ethylene (origin: Alphagas, quality N25). The temperature was kept constant at 20 C. The medium was stirred at ambient temperature for 2 hours, then the excess ethylene was slowly purged by returning to atmosphere pressure at a temperature not exceeding 20 C. and the autoclave was again placed under an atmosphere of argon. The products were separated from the ionic liquid by adding 2 to 3 ml of heptane distilled over CaH2 and degassed. An aliquot (100 mul) of the extracted solution was passed through a short silica column (2 cm) eluted with diethyl ether. It was analyzed by gas phase chromatography (ZB-1 column, 100% dimethylpolysiloxane, 30 metres, helium vector gas 2 ml/min, temperature programming: 60 C. then 5 C./min to 220 C.) coupled to a mass spectrometer. The methyl oleate conversion was 95%. It was calculated using decane as an internal reference. The reaction products were composed of 1-decene (fraction A) and methyl decenoate (fraction B). The presence of 1-decene isomers was not detected. Homo-metathesis products were present in trace amounts and could not be quantified.
