The Color of N-(4-Nitrophenacyl)arylamines

Kallmayer, Hans-Joerg,Wagner, Eugen

, p. 315 - 323 (1980)

The N-(4-nitrophenacyl)arylamines 5, prepared from the arylamines 3 and 4-nitrophenacyl bromide (2), have a yellow, red or violet color, depending on the nature of the aryl substituents.The color is explained by intramolecular interaction of the electron accepting nitrobenzoyl group and the electron donating arylamine part of the molecules.On acetylation of the amino group the color is lost.There are no indications for an equilibrium between the amines 5 and N-(4-nitrostyryl)-arylamines 7.
