3‐substituted‐ and 3,4‐disubstituted‐4,5‐dihydro‐1,2,4‐triazol‐5‐ones (seven being new compounds) were synthesized and their proton magnetic resonance spectra were measured in trifluoroacetic acid (TFA). The protonation shifts observed on comparison of the spectra run in DMSO‐d6 and TFA were attributed to an amidinium‐type resonance of the resulting cations in the acidic medium.
