The oxidation of several fluoroanilines with potassium ferricyanide 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.

1,2,3,4,5,6,7,8-Octafluorophenazine (F-Phen) has an absorption spectrum in the longer wavelength extending to the visible-light region and has a more positive oxidation potential than for unfluorinated phenazine. F-Phen has been photolysed with water in a

Oxidation of pentafluoroaniline by aqueous sodium hypochlorite under phase-transfer conditions gave decafluoroazobenzene (2), octafluorophenazine (3), and the dark red N-chloro-N'-(pentafluorophenyl)-2,3,5,6-tetrafluorobenzo-1,4-quinone di-imine (4) as a mixture of Z- and E-isomers.X-Ray diffraction studies revealed that this chloro imine gives crystals containig both isomers, the structures of which have been solved.Singlet pentafluorophenylnitrene is proposed to be an intermediate in the oxidation reaction whereby compounds (2), (3), and (4) are formed following nucleophilic attack by pentafluoroaniline on the nitrogen atom, and the ortho- and para-positions respectively.A convenient, albeit not high yielding, procedure for the preparation of decafluoroazobenzene is described.
