Versuchsvorschrift

31.5 g of 4-(4-phenyl-4-n-propyl-4-silacyclohexyl)cyclohexanone was dropped in 120 ml of a solution of 1.0 mole of p-fluorophenylmagnesium chloride in tetrahydrofuran at a temperature of 40° to 50° C. After agitation at 50° C. for 2 hours, the reaction mixture was poured into a saturated ammonium chloride aqueous solution, followed by extraction with benzene. 1.0 g of p-toluenesulfonic acid monohydrate was added to the benzene phase, followed by distilling off the resultant water under reflux. When the distilling of water stopped, the benzene solution was washed with a sodium hydrogencarbonate aqueous solution, dried and concentrated to obtain crude 4-(4-(4-fluorophenyl)-3-cyclohexenyl)-1-phenyl-1-n-propyl-1-silacyclohexane. This product was dissolved in 100 ml of ethanol and hydrogenated in the presence of 1.0 g of a palladium-carbon catalyst, followed by separation of the catalyst by filtration and concentration to obtain 35.0 g (yield: 88%) of 4-(4-(4-fluorophenyl)cyclohexyl)-1-phenyl-1-n-propyl-1-silacyclohexane. The results of IR analysis are shown below.
