Alkylamines and amides are readily prepared by nucleophilic aromaticsubstitution of hydrogen in nitroarenes by electrochemical oxidation. Useful yields (15−85%) are achieved in a simple direct and regioselective amination process. The synthetic method has been examined in the absence and presence of external bases, used to promote the first step of the nucleophilic aromaticsubstitution reaction, i.e

Useful yields are achieved in the regioselective direct formation of anilines and aromatic amides through hydrogennucleophilicaromaticphotosubstitution of m-dinitrobenzene with primary amines and amides, promoted by fluoride anion.
