Conclusions

  1. 1.

    The possibility of forming radical cations of diarylamines in the oxidation of DPA and its derivatives has been demonstrated by means of ESR.

  2. 2.

    In the oxidation of 4-sulfodiphenylamine in 8 N H2S4, the ESR spectrum of the reaction mixture can be assigned to a cation radical of the tetraarylhydrazine; in the oxidation of N-methyl-4-sulfodiphenylamine, the spectrum can be assigned to a cation radical of the N,N'-diarylbenzidine.

  3. 3.

    The ESR data obtained in this work are consistent with an oxidation mechanism that includes intermediate radical stage.
