The preparation of novel 2-(fluoroanilino)-1,4-naphthoquinones is presented. It takes place under mild conditions by reacting the corresponding fluoroaniline and 1,4-naphthoquinone in the presence of a Lewis acid catalyst with strong oxidation properties such as CeCl3·7H2O. This preparation was also investigated under microwave irradiation. All 1,4-naphthoquinone derivatives were characterized by UV–Vis, IR, 1H and 19F NMR, MS and cyclic voltammetry, to investigate the effect of the fluoro-substituents on their electronic properties.
