Urea‐2,2‐dihydroperoxypropane as a Novel and High Oxygen Content Alternative to Dihydroperoxypropane in Several Oxidation Reactions

Abstract

Urea‐2,2‐dihydroperoxypropane (UDHPP)‐ a white crystalline solid oxidant which is formed when urea is recrystallized from dihydroperoxypropane‐ was applied as the terminal oxidant in several oxidative procedures namely epoxidation of α, β‐unsaturated ketones and alkenes, oxidation of sulfides to sulfoxides and sulfones, bayer‐villeger reaction, bromination and iodation of aniline and phenol derivatives, oxidative esterification, oxidative amidation of aromatic aldehydes, thiocyanation of aromatic compounds, and oxidation of pyridines, oxidation of secondary, allylic and benzylic alcohols. All the approaches were carried out under mild conditions and short reaction times and afforded the corresponding products in high yields.
