Abstract

The reaction of 1,1-dihydropolyfluoroalkyl benzyl sulfones with sodium azide or trimethylsilyl azide in the presence of tertiary amines gives ammonium salts of 4-benzylsulfonyl-5-polyfluoroalkyl-ѵ-triazoles. The proposed reaction scheme includes the participation of catalytic amounts of azide ion in the cyclization of the formed intermediate vinyl azides to triazoles. X-ray analysis of 1,4‑diazabicyclo[2.2.2]octane salt of 4-benzylsulfonyl-5-(ω-H-hexafluoropropyl)-ѵ-triazole has been carried out.
