RING-RING AND RING-CHAIN TAUTOMERISM IN THE THIOBENZOYLHYDRAZONES OF ALIPHATIC β-DICARBONYL COMPOUNDS

The 5-hydroxy-4,5-dihydropyrazole-2,3-dihydro-1,3,4-thiadiazole ring-ring tautomeric equilibrium in solutions was investigated by NMR spectroscopy for the products from the condensation of thiobenzohydrazide with aliphatic β-dioxo compounds.In polar media (DMSO) ring-chain tautomeric equilibrium involving the enehydrazine or hydrazone tautomers is also observed in individual cases. 1-Phenylthioacetyl-3,5-dimethyl-5-hydroxy-4,5-dihydropyrazole is formed during the condensation of acetylacetone with phenylthioacetylhydrazine, and 1-thiobenzoyl-3-acetylacetamidrazone was obtained from thiobenzoylhydrazide and monothiodiacetamide.
