Versuchsvorschrift

To a 20 ml toluene solution of 51.93 g (0.48 mole) of 4-vinylcyclohexene-1 and 0.37 g of 5% H2PtCl6 in t-amyl alcohol is added 33.6 (0.23 mole, 90% purity) of 1,1,3,3-tetramethyldisiloxane at 45° C. to 50° C. for 1 hour and 30 minutes. The reaction is complete after maintaining the reaction at 55° C. for 5 hours. To this mixture is added 250 ml methyl ethyl ketone. After washing successively with four 100 ml portions of H2O, 78 g (>95% purity by GC) of 1,3-bis-((2-cyclohexenyl)-ethyl)-1,1,3,3-tetramethyldisiloxane having a light yellowish color is obtained after stripping off solvent at 120° C. and <10 mm Hg. The structure of the product, 1,3-bis-((2-cyclohexenyl)ethyl-1,1,3,3-tetramethyldisiloxane, is confirmed by IR and 1H NMR as follows:
