Abstract
The process of oxidizing organic compounds by dissolving the organic compound in a water-immiscible, inert organic solvent and contacting same with an aqueous hypohalite ion in the presence of a catalytic amount of a quaternary onium salt is improved by employing a primary alkyl ester as the organic solvent. For example, cyclohexylmethylamine is oxidized under mild conditions to a high yield of cyclohexylnitrile by dissolving the amine in ethyl acetate and contacting same with aqueous hypochlorite and in the presence of a catalytic amount of tetra-n-butylammonium chloride.
