Article abstract of DOI:10.1246/bcsj.60.201

Fragmentation of 3,5-dinitro-2-pyridone (1) by primary amine gave nitroacetamide (2) and nitromalonaldehyde diimine.In the case of N-methyl derivative (1c), the reaction was completely suppressed by the product 2 to give an anionic ?-adduct of 1c with 2.T
