The product of condensation of thiobenzhydrazide with methyl acetoacetate and its α-alkyl-substituted homologs have the structure of the corresponding 2,3-dihydro-1,3,4-thiadiazoles; only the derivative of α-isopropylacetoacetic acid ester has the open hydrazone form.The products of the reaction of thiobenzhydrazide with the methyl ester of 2-oxocyclopentane- and 2-oxocyclohexanecarboxylic acid are mixtures of enehydrazine and thiadiazoline forms; the percentage of the latter decreases in polar solvents.
