The previously undescribed hydrazones of 3-(2-hydroxyphenyl)- and 3-(2-hydroxy-1-naphthyl)propenals were synthesized.It was shown by IR, UV, and PMR spectroscopy that they exist in the crystalline state and in solutions in the form of the syn-s-trans isomer of the benzenoid hydroxyhydrazone structure.In the gas phase using mass spectrometry the presence of two structural isomers, one having the cyclic 2-hydrazino-2H-chromene structure and one having hydroxyhydrazone structure, was definitely determined.
