The formation of episulphones fran the corresponding episulphides by oxidation with hydrogen peroxide is well docwnented (1). Only recently, however, has a successful partial oxidation procedure been reported (2) for the preparation of a number of episulphoxides.

We recently reported' that acctanilide readily sulphonatcs in solutions of sulphuric acid > 70 per cent I& to form I+acetylsulphanilic acid , and noted that the rate of hydrolysis of this latter compound increased with increasing acidity beyond 80 per cent d= sulphuric acid. Ve have now prepared IG
Haake and Tyssee' postulated a dissociative (Al or Al-like) mechanism for the acidcatalysed hydrolysis of diphenylphosphinanilides 1. They considered cleavage of theP-N bond in the protonated anilide to be well advanced in the transition state 2 and nucleophilic participation by water to be small. A
