Abstract

3-Amino-5-trifluoromethyl-1,2,4-triazole has been utilized for the syntheses of poly-substituted 2-trifluoromethyl-[1,2,4]triazolo[1,5-a] pyrimidine derivatives, via its reactions with acrylonitrile derivatives and various 1,3-dicarbonyl compounds, and of trifluoromethyl[1,2,4]triazolo[5,1-c]triazine derivatives, via its diazotization and coupling with active methylene reagents.
