2, 4-Ionene Supported Permanganate: A Novel, Efficient and Selective Solid Phase Oxidizing Agent for Oxidation of Organic Compounds

Abstract 2, 4-ionene supported permanganate is easily prepared by treatment of 2, 4-ionene with an aqueous solution of potassium permanganate. This reagent could be used as a stable, mild and efficient oxidizing agent to produce carbonyl compounds from hydroxyl compounds or arenes, and disulfides from thiols in either heterogonous or solvent free conditions. In addition, aromatization of different types of 2-arylimidazolines and 2-alkylimidazolines to corresponding imidazoles was achieved in good yields in acetonitrile at room temperature.
