The oxidation of several fluoroanilines with potassiumferricyanide and potassium hydroxide is described. In this oxidation, the major products are fluoroazobenzenes. In the case of 2-fluoro-substituted anilines, heterocyclic fluorophenazines were obtained in low to moderate yields. The optimal conditions for the reaction and the mechanism are presented.Key words: oxidation, fluoroanilines, fluoroazobenzenes
