Potassium chlorochromate on a solid support: a convenient and mild reagent for the oxidation of alcohols

The oxidation of primary and secondary alcohols by potassium chlorochromate supported on alumina or silica gel is reported. The results indicate that the yields in some cases depend on the support medium. Benzylic and secondary alcohols are oxidized in the best yields. The effect of solvent on the reaction is discussed and the conclusion is drawn that the best yields are obtained in non-polar solvents
