Conclusions

  1. 1.

    The copper bis(salicylaldiiminate)s are involved in repeated chain rupture acts in the course of the oxidation of cyclohexylamine by α-aminoperoxide radicals.

     
  2. 2.

    Measured by the initiated oxidation method, the rate constants for one-electron oxidation and reduction of α-aminoperoxide radicals by Cu(I) and Cu(II) complexes diminish with an increase in the electron-donor activity of the substituent in the imine component of the coordinated Schiff base.

     
  3. 3.

    Measured in this same way, the rate constant for chain rupture in the p,p′-substituted diphenylamines increases with an increase in the electron-donor activity of the substituent.
