Versuchsvorschrift

To 500 ml of toluene in a 100 ml round bottom flask, fitted with a condenser and magnetic stirrer, are added 7.6 g (0.03M) of the potassium salt of 4-hydroxy-4'-nitrobiphenyl, 36.6 g (0.15M) of 1,6-dibromohexane, and 0.5 g of 18-crown-6 ether. The mixture is refluxed for about 20 hours, and then filtered hot. The solvent is evaporated, and the residual crude product is recrystallized from hexane to provide purified product.
