Abstract:A number of N-acetyloxypyridinium salts has been studied, using molecular spectroscopy methods. These compounds exist in solutions of bipolar solvents as ions and ion pairs of various structure. The association to ion pairs effects the frequences and intensities of characteristic vibrations, the chemical shifts of proton peaks, and the reaction rate of symmetric exchange of acetyl groups. Based on the spectrochemical correlations, data on the structure of the salts, the acetyl exchange reaction mechanism, and the influence of the solvent nature, the reagent structures, the additions of the base electrolyte and crown-ether on its kinetic characteristics have been obtained.
