Abstract: Disclosed is a method of producing an organic compound. The method uses a metathesis catalyst in a coupling reaction of an olefin. The method comprises the steps of introducing the olefin into a container; either placing the container under vacuum or bubbling a gas through the olefin; adding an additive with the olefin; mixing the olefin and the additive, the mixing creating a mixture; adding an amount of the metathesis catalyst to the mixture, the amount being less than about 100 ppm by weight of the mixture; and optionally heating the mixture to a temperature, the temperature being greater than room temperature.

Abstract: Polyhedral oligomeric silsesquioxanes (POSS) linked ligand of the general formula (I) L[(R1a)n-1(SiO1,5)nR2a]k[(R1b)n-1SiO1,5)nR2b]l[(R1c)n-1SiO1,5)nR2c]m??(I) in which (R1a,b,c)n-1(SiO1,5)n is a polyhedral oligomeric silsesquioxanes (POSS) with n=4, 6, 8, 10, 12, 14, 16 or 18 and R1a, R1b, R1c is each independently selected from the group consisting of same or different branched or linear C1-C20 alkyl chains, cyclo alkyl, C1-C20 alkoxy, aryl, aryloxy, heteroaryl and arylalkyl groups, k, l, m is 0 or 1 provided that k+l+m?1, R2a, R2b, R2c is a spacer that binds the polyhedral oligomeric silsesquioxane (POSS) to the ligand L and ligand L is an uncharged electron donor.
