Generation of nitrile oxides from oxime derivatives by the oxidation with ammonium hexanitratocerate(IV)

Article abstract of DOI:10.1246/bcsj.72.2277

Aromatic and aliphatic nitrile oxides are generated by the oxidation of α-hydroxyimino carboxylic acid with ammonium hexanitratocerate(IV). They react with olefinic and acetylenic dipolarophiles to give the corresponding cycloaddition products in good yield. The oxidation of α-oxo aldoximes also affords α-oxo carbonitrile oxides.
