The incorporation of nitrogen atoms into the aryl rings of conventional diphenylamine antioxidants enables the preparation of readily accessible, air-stable analogues, several of which have temperature-independent radical-trapping activities up to 200-fold greater than those of typical commercial diphenylamines. Amazingly, the nitrogen atoms raise the oxidation potentials of the amines without greatly changing their radical-trapping (H-atom transfer) reactivity.
Preparation of diarylamines by the addition of 4-(N,N-dimethylamino)phenyllithium to nitroarenes

The addition of 4-(N,N-dimethylamino)phenyllithium to nitroarenes in THF (-78°C) affords the corresponding diarylamines in one-pot and the reaction appears to be general in scope. A 'nitroso'-based mechanism is proposed for this novel nitroreductive N-arylation reaction.
