The proton magnetic resonance spectra of 12 azoles were measured in neutral and acidic solvents. The protonation shifts observed by comparison of the spectra in DMSO-d6 and TFA were attributed to an amidinium type resonance of the resulting cations. The synthesis and characterization of the azoles are also discussed.
