Abstract
Unsaturated heterocyclic carbonyl-containing compounds, e.g., 2H-imidazol-2-ones, 2(3H)-oxazolones and 2H,3H-pyrrol-2-ones, are prepared by the anodic oxidation of saturated heterocyclic carbonyl-containing precursors of the above compounds in a C.sub.1-4 alcohol or carboxylic acid solvent in the presence of a supporting electrolyte followed by dehydrosubstitution of the alkoxy- or acyloxy-substituted intermediate. The products formed may be polymerized or copolymerized with other ethylenically unsaturated monomers to prepared resins, films, etc. or they may be employed as intermediates for the preparation of various biologically active compounds.
