Participants

Procedure

67 g (0.5 mol) of aluminium chloride are added in portions to a mixture of 80 g (0.5 mol) of cyclohexylbenzene 70 g (0.5 mol) of benzoyl chloride and 500 ml of methylene chloride at room temperature. After 15 hours, the reaction mixture is poured onto ice/hydrochloric acid. The organic phase is washed with water until neutral, dried over sodium sulphate and evaporated. The crude product is purified by distillation. 93.3 g (75% of theory) of 4-cyclohexylbenzophenone of boiling point 160° to 175° C./0.1 mm are obtained.
