Versuchsvorschrift

38.8 g (0.15 mol) of 4-phenylbenzophenone are dissolved in 200 ml of ethanol and 3 g (0.075 mol) of sodium borohydride are added. After heating for 15 hours under reflux, and allowing to cool, the reaction mixture is hydrolyzed with water containing a little hydrochloric acid. The solid thereby produced is purified by recrystallization from ethanol. 36 g (89% of theory) of (biphenyl-4-yl)-phenyl-carbinol [alternatively named as diphenyl-phenyl carbinol or α-(biphenyl-4-yl)benzylalcohol] of melting point 72°-73° C. are obtained.
