Polarographic study of certain N-oxide free radicals

Conclusions

  1. 1.

    Stable free radicals — N-oxides of 2,2,6,6-tetramethylpiperidone and 2,2,6,6-tetramethylpiperidine — are irreversibly reduced on a dropping mercury electrode to the corresponding hydroxylamine derivatives, giving one-electron, one-stage diffusion waves.

  2. 2.

    The heights of the waves do not depend on the pH; E1/2 of the waves are determined by the kinetic volume protonation of the radicals, preceding the strictly electrochemical step. The introduction of adsorbed anions (Cl, Br) into the solution, produces a displacement of E1/2 of the waves, equal to the change in the ψ1-potential.
