Benzyltriphenylphosphonium peroxodisulfate (PhCH2PPh 3)2S2O8: An efficient and convenient reagent for the oxidative cleavage of phenylhydrazones, paranitrophenylhydrazones, and semicarbazones to their parent carbonyl compounds

Abstract

Deprotection of phenylhydrazones, paranitrophenylhydrazones, and semicarbazones to their parent aldehydes and ketones in high yields has been carried out using benzyltriphenylphosphonium peroxodisulfate as a selective oxidant under mild conditions.
