The reaction of α,α-difluoroazides with acetylenic compounds

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.
