Procedure

The procedure of Example I was repeated, but this time cobalt (II) acetate tetrahydrate (0.008 moles), sodium bromide (0.04 moles), diphenylmethane (0.055 moles) and hydrogen peroxide (35%, 0.28 moles) were used. The final reaction mixture, analysed by HPLC, revealed that 91.5% of the diphenylmethane had been consumed, yielding products including benzophenone (72.3% yield).
