Diphenyldichloromethane is an organic compound with the formula (C6H5)2CCl2. It is a colorless solid that is used as a precursor to other organic compounds.
It is prepared from carbon tetrachloride and anhydrous aluminium chloride as catalyst in a double Friedel-Crafts alkylation of benzene. [3] Alternatively, benzophenone is treated with phosphorus pentachloride: [4]
It undergoes hydrolysis to benzophenone. [3]
Reductive dehalogenation of diphenyldichloromethane with copper or with nickel gives tetraphenylethylene: [5] [6]
