Participants

Reaction Steps

To a 10 ml toluene solution of 60.1 g (0.5 mole) of 5-vinyl-2-norbornene and 0.30 g of 5% H2PtCl6 in t-amyl alcohol is added 29.6 g of 1,1,3,3-tetramethyldisiloxane (0.22 mole, 90% purity) at 45°-50° C. for 1 hour and 30 minutes. The reaction is complete after keeping the reaction at 55°-60° C. for 6 hours. The mixture is then dissolved in 250 ml methyl ethyl ketone. After washing successively with 100 ml portions of water four times, 65 g of 1,3-bis(5-vinylnorbornyl)-1,1,3,3-tetramethyldisiloxane is obtained after stripping off solvent at 120° C./110 mm Hg. The structure of the product is confirmed by IR and 1H NMR as follows:
