STUDY ON THE SYNTHESIS OF UREA-HYDROGEN PEROXIDE AND APPLICATION FOR OXIDATION OF BENZYLIC ALCOHOLS UNDER MICROWAVE ACTIVATION
Keywords:Oxidation reaction, benzylic alcohols, benzoic derivatives, Urea-Hydrogen Peroxide
The Urea-Hydrogen Peroxide complex was synthesized from urea, hydrogen peroxide by using microwave assisted method and characterized by FT-IR. This Urea-Hydrogen Peroxide complex could be employed as an oxidizing agent for metal-free oxidation reaction of benzylic alcohols to carboxylic acids corresponding. This oxidation protocol, carried out under alkaline-water in microwave oven in presence of iodine as a catalyst, was efficient and compatible with a range of benzylic alcohols to afford a direct access to benzoic derivatives in very good yields up to 95.4% and high selectivities.
