Abstract
p-Phenylenediamine reacts with Sanger’s reagent in hot ethanol to give the expected monoand di-substitution products, but in ethanol at rt it gave exclusively 2-nitro-5-fluorophenyl-pphenylenediamine where a hydrogen atom is displaced by attack at an activated, unsubstituted position. The reactions of p-phenylenediamine and aniline with Sangers reagent were compared in the cheap, ‘green’ solvent ethanol.
