Graphic abstract: Trifluoroacetyl substituted pyrazolotriazines: synthesis and pathways of formation

Abstract: The reaction of 4-dimethylamino-1,1,1-trifluorobut-3-en-2one with 3-arylpyrazole-5-diazonium salt in MeCN affords 7-aryl-3-(trifluoroacetyl)pyrazolo[5,1-c][1,2,4]triazines. The transformation of relative 5-diazopyrazoles leads to 4-hydroxy-1,4-dihydropyrazolo[5,1-c][1,2,4]triazine derivatives, while the reaction in acidic aqueous solution results in 4,4,4-trifluoro-3-oxo-2-(pyrazol-5-ylhydrazono)butanals.

Keywords: pyrazoles, diazo compounds, diazonium salts, enones, pyrazolo[5,1-c][1,2,4]triazines, trifluoromethyl group.
