Abstract
The strong electron withdrawing nature of a 2,4-dinitrophenylamino group when attached to a chloro-naphthoquinone enhances the displacement of the chlorine atom by various aliphatic, cyclic and aromatic amines. A new series of 2-amino-3-(2,4-dinitrophenylamino) derivatives of 1,4-naphthoquinone were prepared. Three absorption maxima in the UV-vis spectra were typical, including one at 430-550 nm assigned to a CT transition.
