Abstract: Pyrazoles bearing (2,3,5,6-tetrafluoropyridinyl)thio group were obtained from 3-aminopyrazoles. The reaction is performed by diazotization of starting amines followed by treatment of the intermediate diazonium salts with 2,3,5,6-tetrafluoropyridine-4-thiol and potassium carbonate. The method is best applied towards 4-substituted 3-aminopyrazoles.

Keywords: pyrazoles, aminopyrazoles, sulfides, diazonium ions, organofluorine compounds, pyridines.
