Conclusions

  1. 1.

    The reactions of acid disproportionation of piperidinooxyls and the interaction of 1-oxo with 1-hydroxypiperidinium salts are reversible and proceed through an intermediate 1-hydroxypiperidmylium cation according to a general kinetic scheme.

     
  2. 2.

    The rate and equilibrium constants were determined for the reaction of acid disproportionation of 2,2,6,6-tetramethylpiperidino-1-oxyl.
