Benzophenone derivatives having the formula R-C6H4-CO-C6H4-R used as intermediates of fine chemicals are prepared from 1,1-bis (aryl)- 2,2,2-trichloroethanol (III). This is done by treating them with alkali, e.g., hydroxide or carbonate of alkali metal, in water or an organic solvent at 0 - 200 ≦̸C; where R = H, halogen, alkyl, phenyl, alkoxy, or phenoxy. The mole ratio of alkali to (III) is 0.2 - 10.
