Synthesis
It is prepared from carbon tetrachloride and anhydrous Aluminium chloride as catalyst in a double Friedel-Crafts alkylation of benzene. Alternatively, benzophenone is treated with phosphorus pentachloride:
(C6H5)2CO + PCl5 → (C6H5)2CCl2 + POCl3Reactions
It undergoes hydrolysis to benzophenone.
(C6H5)2CCl2 + H2O → (C6H5)2CO + 2 HClIt is used in the synthesis of tetraphenylethylene, diphenylmethane imine hydrochloride and benzoic anhydride.
