Abstract
Reduction of nine N-substituted oximes (nitrones) I–IX and of seven O-substituted oximes XI–XVII at the dropping mercury electrode was investigated. Aromatic N-substituted derivatives are reduced in acid as well as in alkaline media in one four-electron wave to the secondary amine; the reduction proceeds through the corresponding Schiff base. The behaviour of aromatic O-alkyl derivatives in acid media is similar to that of corresponding N-alkyl derivatives whereas in alkaline solutions O-alkyl derivatives do not show a reduction wave. Aliphatic N-derivatives are reduced in acid media only and aliphatic O-derivatives are principally polarographically inactive. In all instances, both isomeric derivatives can be safely distinguished by polarography.
