Abstract 1, 3-Dinitrobenzene and some its 2-and 4-substituted derivatives are dehydroaminated in a solution of potassium permanganate in liquid ammonia to give the corresponding mono-or diamino-1, 3-dinitro-benzenes. Under the same conditions, 4-fluoro- 1, 3-dinitrobenzene is converted into 2, 4-dinitroaniline via replacement of the fluorine atom, while 2, 4-dinitrobenzaldehyde gives rise to 2, 4-dinitrobenzamide.
