Effect Of Substituents

Ethyl (3-substituted 5-thioxo-1,2,4-triazolin-4-yl)acetates were prepared by addition-cyclization reaction of ethyl isothiocyanatoacetate with carboxylic acid hydrazides in the presence of sodium ethoxide. Thermal cyclization of the adduct in dimethylformamide afforded 1-acetamido-2-thiohydantoin. The effect of substituents on the cyclization course and the thione-thiol tautomerism are discussed.

Cyclization Reactions

Reactions of carbonyl isothiocyanates with enamines of the type CH3-C(NH2)=CH-X (X = CN, COOC2H5, or COCH3) were investigated. The formation of products of AdN, SN, and cyclization reactions is discussed on the basis of their IR, UV and mass spectra. In one case, the thermal cyclization was followed by differential thermal analysis.
