Methylammonium chlorochromate adsorbed on silica gel is described and evaluated as a convenient reagent for efficient oxidation of a variety of primary and secondary alcohols. This reagent is easily prepared and very stable. Primary and secondary alcohols are oxidized by the reagent into corresponding carbonyl compounds in good yields. The oxidation of alcohols with the reagent can proceed easily in some solvents, the oxidation condition is mild and the products are unique and easily separated.
