Аннотация
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.
