1,3‐Dichloro‐5,5‐dimethylhydantoin (DCDMH) as a New Oxidizing Agent for the Facile and Selective Oxidation of Oximes to Their Carbonyl Compounds

Oximes are converted to the parent carbonyl compounds in good yields when treated with 1,3‐dichloro‐5,5‐dimethylhydantoin (DCDMH) ( 1 ). An optimized procedure has been developed; the simple work‐up minimizes loss of product and oximes have been selectively oxidized in the presence of alcohols and alkenes.
