Arylamination of 3-nitropyridine via the nucleophilic substitution of hydrogen leads to a mixture of 2-arylamino-5-nitropyridines and novel 2-arylamino-5-nitrosopyridines, with the latter as the major product. The proposed mechanism includes the formation of σ H -adducts and their further aromatization proceeding either through an oxidative pathway or intramolecular Red/Ox pathway of the S NH reaction. Moreover, we have shown that nitroso compounds can be selectively oxidized with m -chloroperbenzoic acid to give the corresponding nitro derivatives or their N -oxides, depending on the reaction temperature and the amount of oxidant.
