KINETICS AND MECHANISM OF OXIDATION OF ALIPHATIC ACETALS WITH PEROXOMONOSULFATE

The oxidation of fifteen aliphatic acetals of normal aliphatic aldehyd es and substituted aliphatic aldehydes with aliphatic and substituted aliphatic as well as with aromatic alcohols by peroxomonosulphate in a queous acetic acid medium is first order each in [oxidant] and [acetal ] and yields the corresponding esters as the main product. The oxidati on reaction is independent of change in dielectric constant of the med ium. The activation enthalpies and entropies of the reactions are line arly related. A mechanism involving hydride ion shift is proposed.
