Herein, the syntheses of various functionalized 1,3-diisopropyltriaz-1-enes is described. This simple transformation tolerates a vast number of functional groups (e.g., halides) and allows the syntheses of 1,3-diisopropyltriaz-1-enes starting from commercially available aniline derivatives. These substrates are suitable for a range of silver-mediated perfluoroalkylation reactions.

of silver(I) fluoride, highly fluorinated olefins react readily under solvent-free conditions with arenes via CH-substitution. This transformation could be used to synthesize various methoxycarbonyltetrafluoroethylated aromatic triazenes and anisoles under high functional group tolerance. The method could be applied to the synthesis of a formal fluorinatedbioisostere of the NSAID flurbiprofen. To
