Procedure

A mixture of 5 mmol of benzhydrol, 0.5 mmol of N-hydroxyphthalimide, and 5 ml of ethyl acetate was stirred at 75° C. in an air atmosphere (10 atm) for 12 hours. An iodometric analysis of a reaction mixture revealed that hydrogen peroxide was formed in yield of 57% (selectivity: 76%). Separately, as a result of a gas chromatographic analysis of the reaction mixture, the conversion rate from benzhydrol was 75%, and benzophenone was formed in yield of 75%.
