Abstract
1,2,4-Triazolo[3,4-b]-1,3,4-thiadiazines, hydrazones, and β-thio adducts were obtained by reactions of 4-amino-3-mercapto-1,2,4-triazole with ω-bromoacetophenones, aldehydes, and α,β-unsaturated ketones. Conditions that promote the cyclocondensation of the β-thio adducts to the previously undescribed 1,2,4-triazolo[3,4-b]-1,3,4-thiadiazepines were found. The chemical and spectral properties of the compounds obtained are discussed.
