The oxidative amination of 3-nitropyridines
3-Nitropyridine was reacted with ammonia or alkylamines and KMnO4 under several different conditions. Substitutions in the para position to the nitro group were obtained with high regioselectivity: with ammonia, 2-amino-5-nitropyridine (66%), w

Regioselectivity of the Amination of Some 3-Nitropyridines by Liquid Ammonia / Potassium Permanganate
3-Nitropyridine and some of its derivatives are aminated in a liquid ammonia solution of potassium permanganate to the corresponding 2- and (or) 4- and (or) 6-amino compounds.Quantumchemical calculations for a few 3-nitropyridines suggest that the experimentally observed regioselectivity of the amination is controlled by Coulombic interaction. --- Key Words: Amination / Nitropyridines / Reactivity indices / Calculations, MNDO
