Reaction Steps

A mixture of 1.062 g (10 mmol) of ethylbenzene, 0.205 g (1 mmol) of N-acetoxyphthalimide, 0.025 g (0.1 mmol) of cobalt(II) acetate tetrahydrate, 0.025 g (0.1 mmol) of manganese(II) acetate tetrahydrate and 15 ml of acetic acid was stirred at 130° C. in an atmosphere of air [2 MPa (gauge pressure)] for 8 hours and thereby yielded benzoic acid in a yield of 85% (analyzed by gas chromatography) with a conversion from ethylbenzene of 96%. In this procedure, acetophenone was not produced.
