Procedure

The ethylenolysis of methyl oleate was used as a test to determine the activity of (PCy3)Cl2Ru(3-pentafluorophenyl-6,8-diisopropoxyinden-1-ylidene). A catalyst compound stock solution (0.1379 mM) was made by dissolving the catalyst compound in anhydrous dichloromethane. Methyl oleate (0.87 g, 1.0 mL), catalyst compound stock solution (0.906 g), dichloromethane (4.12 g), and tetradecane (0.152 g) as an internal standard were placed in a Fisher-Porter bottle equipped with a stir bar. The vessel was then filled with ethylene to 150 psig and placed in an oil bath heated to 40° C. for 3 hours. The vessel was then depressurized and 5 drops ethyl vinyl ether added to stop the reaction. A sample was analyzed by gas chromatography. The cross-metathesis reaction yielded 18.5% 1-decene and methyl-9-decenoate with 99% selectivity 1-Decene and methyl-9-decenoate yields corresponded to 4300 turnovers of decene per equivalent of ruthenium.
