SYNTHESIS OF 1,2,4-TRIAZOLO-1,3,4-THIADIAZEPINES AND 4-AMINO-3-ACYLVINYLTHIO-1,2,4-TRIAZOLES BY REACTION O ACYLACETYLENES WITH 4-AMINO-3-MERCAPTO-1,2,4-TRIAZOLE

Glotova, T. E.,Nakhmanovich, A. S.,Romanenko, L. S.,Sigalov, M. V.

, p. 795 - 798 (2007/10/02)

1,2,4-Triazolo-1,3,4-thiadiazepines have been prepared by treating α-acetylenic ketones with 4-amino-3-mercapto-1,2,4-triazole in glacial acetic acid.Terminal acetylenic ketones react with the triazole to form 4-amino-3-acylvinylthio-1,2,4-triazoles.Heating the latter with hydrazine hydrate in alcohol yields substituted pyrazoles.
