Preparation, identification and application of 1,5-bis triphenylphosphonium pentane peroxodisulfate in oxidation of benzylic alcohols

Oxidation of alcohols is the foundation of synthetic chemistry and a fundamental transformation in organic synthesis.1The readily available peroxodisulfate ion, S2O82-,is an excellent and versatile oxidant for a variety of organic and inorganic compounds.2 Some reported successful examples of oxidation with this oxidant are: oxidative decarboxylation of acids, aromatic hydroxylation,oxidation of carbon-nitrogen double bonds, oxidation of alkyl benzenes, alkenes, amines and alcohols.31,5 - bis triphenyl phosphonium pentane peroxodisulfate was synthesized as a new , mild and efficient oxidizing reagent and characterized by IR and NMR spectroscopy.Physico-chemical stability, good selectivity and simple work up are some of advantages of this salt.It has been used in oxidation of different benzylic alcohols to their corresponding carbonyl compounds and the result indicates that oxidation reaction takes place selectively with high yield and simple work up in short time.
