With copper(l) chloride; | 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 98percent) 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 5percent 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, 100percent 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 95percent. 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. |
