2-Imidazolinylhydrazones of salicylic aldehyde, 2-N-tosylaminobenzaldehyde, and 1-phenyl-3-methyl-4-formylpyrazolone-5 are synthesized and studied by the IR, NMR, and electronic spectroscopy. Quantum chemical calculations of geometry and total energy of possible tautomers in a vacuum and ethanol solution are carried out. It is shown that in all cases diazine tautomers are the most stable.
