Abstract According to data from the1H and13C NMR spectra in nonpolar media and the mass spectra, alkylidene derivatives of thiobenzhydrazide have a 1,3,4-thiadiazol-2-ine structure rather than a thiobenzhydrazone structure. The products of condensation of thiobenzhydrazide with acetone and anisaldehyde in methanol undergo partial isomerization to thiobenzhydrazones. The hydrochlorides of the compounds under discussion are the corresponding 1,3,4-thiadiazolinium salts, in which the proton is coordinated with the N4, atom. The 2-phenyl-5,5-dimethyl-1,3,4-thiadiazol-2-ine anion has a noncyclic thioenolate structure.
