Potassium Hydroxide → 4-(4-Methyl-4-propylcyclohexyl)-4'-pentylbiphenyl

Participants

Reaction Steps

A mixture of 3.7 g (0.01 mole) of 4-(4-formyl-4-propylcyclohexyl)-4'-pentylbiphenyl (Example 2), 40 ml of diethylene glycol, 15 ml of 90% hydrazine hydrate and 5.5 g of potassium hydroxide is heated and the hydrazine and water are distilled off until the temperature has risen to about 230° C. The reaction mixture is then boiled for 12 hours and, when cold, 200 ml of water are subsequently added. After customary working up, 4-(4-methyl-4-propylcyclohexyl)-4'-pentylbiphenyl is obtained.
