Conclusions

  1. 1.

    The exchange processes in the pyridine-phosphorylpyridine system were studied by1H and31 NMR. With γ-picoline and phosphoryl-γ-picoline as example, lifetimes of participants in exchange processes at various temperatures were determined.

     
  2. 2.

    In the absence of polyphosphorylpicolinium compounds, chemical exchange between γ-picoline and phosphorylpicolinium can be described by three equally probable processes that include intermolecular exchange as a basic step.

     
  3. 3.

    Thermodynamic exchange parameters were determined. The reactivity of the phosphorylpyridinium derivatives correlates with the basicity of the component pyridine compounds.
