Quinaldinium Chlorochromate(VI), (QnCC) Catalyzed Oxidation of Alcohols with Periodic Acid Under Solvent-Free Conditions and Microwave Irradition

“…Having determined the optimum QnCC amount which maximizes the yield of reaction, the oxidation reactions of various alcohols were examined. As shown in Table 1, all the primary benzylic alcohols (1-7) were almost quantitatively and selectively oxidized to corresponding aldehydes and all the secondary alcohols (8)(9)(10)(11) to ketones with high to excellent yields in very short reaction times with the H5IO6/QnCC system.…”

“…Thus, to date, various oxochromium(VI) amine complexes have been commonly used as stable oxidizing agents for selective oxidation of alcohols with high efficiency. Some of them are pyridinium chlorochromate, pyridinium fluorochromate, pyridinium dichromate, dipyrazinium tris(fluorotrioxochromate), 1-decyl-4-aza-1-azonia-bicyclo[2.2.2]-octane chlorochromate, 3,5dimethylpyrazolium fluorochromate, and triethylammonium chlorochromate (5)(6)(7)(8)(9)(10)(11).…”
