Abstract

Urea-hydrogen peroxide adduct (UHP) is stable, inexpensive and an easily handled reagent. UHP is used in an efficient solid state oxidation of different organic molecules: hydroxylated aldehydes and ketones (to hydroxylated phenols), sulfides (to sulfoxides and sulfones), nitriles (to amides) and nitrogen heterocycles (to N-oxides).
