title = "2,6-Disubstituted 4-azidopyrimidines: synthesis, kinetic and thermodynamic studies of azide-tetrazole rearrangement by NMR spectroscopy",
abstract = "Thermodynamic and kinetic parameters of the tautomeric tetrazole-azide rearrangement for a series of 2,6-disubstituted 4-azidopyrimidines are determined by NOESY/EXSY and DNMR: ΔH = 15—28 kJ mol–1; ΔS = 47—65 J mol–1 К–1; Еa = 93—117 kJ mol–1; lgA = 15.1—18.9. They are dependent on electronic properties of the substituents and the polarity of solvent.",
