Procedure

A mixture of 40 mmol of benzhydrol, 4 mmol of N-hydroxyphthalimide, and 20 ml of ethyl acetate was stirred at 75° C. in an oxygen atmosphere (1 atm) for 12 hours. An iodometric analysis of a reaction mixture revealed that hydrogen peroxide was formed in yield of 60% (selectivity: 85%). Separately, as a result of a gas chromatographic analysis of the reaction mixture, the conversion rate from benzhydrol was 71%, and benzophenone was formed in yield of 70%.
