A new one-step reaction between 1,1-difluoroazides and primary amines is reported as an efficient synthetic approach for tetrazole formation. Examples include the syntheses of fluorine-containing 1,5-substituted tetrazoles from three fluorinated azide precursors and various amines. Greater substituent diversity in comparison with conventional methods is achieved.

Reaction of α,α-difluoroazides — 2H-perfluoropropyl azide and methyl ester of 3-azidoperfluoropropionic acid — with different acetylenes affords 1,2,3-triazoles in high yields. Thermal decomposition of some triazoles leads to products of oxidative aminofluorination.
