Procedure
26.3 g (0.1 mol) of trans-1-bromomethyl-4-n-pentyl-4-silacyclohexane was dripped into a mixture of 2.5 g (0.11 mol) of magnesium and 300 ml of THF to obtain a Grignard's reagent. This solution was then dripped into a 500 ml THF solution of 0.5 g of triethyl phosphate, 0.1 g of copper (I) iodide and 44.4 g (0.1 mol) of 4-(trans-4-iodomethylcyclohexyl)-4'-trifluoromethylbiphenyl. After a conventional after treatment, purification was conducted by means of chromatography to obtain 38.5 g (yield 76.9%) of 4-(trans-4-(2-(trans-4-n-pentyl-4-silacyclohexyl)ethyl)cyclohexyl)-4'-trifluoromethylbiphenyl was obtained.
