Nitroxides (Aminyl Oxides), XLII. — The Isolation of the First OC‐Bonded Dimer of a Vinyl Nitroxide Vinyl nitroxide 2 , formed by oxidation of nitrone 1 , with lead dioxide, affords the OC dimer 3 . Oxidation of 1 proceeds rather slowly. A high oxidation potential is found for 1 . However, if vinyl nitroxide 2 is generated from the vinylhydroxylamine 4 , the aldehyde 7 is formed by a complex reaction sequence.
