Versuchsvorschrift
0.5 mol of 4-(trans-4-pentylcyclohexyl)biphenyl, 500 ml of carbon sulfide and 0.5 mol of aluminium chloride are introduced into a three-neck flask fitted with a dry-ice reflux condenser. After the mixture has been cooled to -30°, 0.5 mol of trifluoroacetyl chloride are condensed in. The mixture is then allowed to warm to 0° and stirred at this temperature for 6 hours then at room temperature for 14 hours. The reaction mixture is poured onto a mixture of ice and dilute hydrochloric acid. The organic phase is separated off, and the aqueous phase is extracted by shaking with dichloromethane (2×50 ml). The organic phases are combined, the solvents removed by distillation and the product is recrystallized twice from ethanol.
