Isomeric 2-nitraminopyridines I (R = 3-Me, 4-Me, 5-Me, 6-Me, 3-NO2, 5-NO2, 5-Cl, 3-CO2H) as well as 3,5-dibromo-2-nitraminopyridine (II, R1 = NO2) rearranged on irradiation with a low pressure Hg lamp (253.7 nm) in MeOH. Preference was generally noted for the migration of the side-chain NO2 group to the vicinal β-position. II (R1 = NO2) gave both II (R1 = H) and the pyridone III. The ratio of the preparative and quantum yields of the two products were 2.5 and 3.0, resp.
