Yield:93-59-4 83%

Reaction Conditions:

Stage #1:dibenzoyl peroxide with sodium in methanol;chloroform at -5; for 0.5 h;Inert atmosphere;
Stage #2: with hydrogenchloride in methanol;chloroform;water

Steps:

1-3
1-3: benzenecarboperoxolc acid; 19 g (78 mmol) of dibenzoyl peroxide are dissolved in 125 ml of chloroform at -5°C. 2.2 g (94 mmol) of sodium dissolved in 50 ml of methanol under a stream of nitrogen are added dropwise. After stirring at -5°C for 30 minutes, ice-cold water is added and the medium is acidified with a 2N aqueous hydrochloric acid solution. Extraction with dichloromethane is carried out and then the organic phase is dried over magnesium sulphate, filtered and concentrated. 9 g of benzenecarboperoxoic acid are obtained in the form of a white solid with a yield of 83%.
