摘要
Oxidation reactions play important roles in organic synthesis, where hydrogen peroxide and peroxy acids are always employed as oxidants. Urea-hydrogen peroxide (UHP) is recently utilized in numerous oxidation reactions as environment-friendly solidified hydrogen peroxide, due to its advantages such as stable at room temperature, high hydrogen peroxide content (36.2%) and the potential for releasing it in a controlled manner. Several applications of UHP to organic synthesis are summarized according to reaction type, especially for epoxidation, Baeyer-Villiger oxidation, N-oxidation, oxidation of sulfides to sulfoxides and sulfones, oxidative-halogenation and so on.
