Preparation of Aromatic Triazenes and Their Application in Silver-Mediated Perfluoroalkylation Reactions
摘要:
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.
ation of functionalized aromatictriazenes is described. Using silver(I)-fluoride and different fluorinated (trimethyl)silyl substituted species, it was possible to synthesize various ortho-fluorinated triazenes in good yields via simple CH-substitution. Initial reactions under solvent-free (neat) conditions indicate a stabilizing interaction between “AgRf” and the triazene moiety, which may be responsible

A silver key to add CF3: In presence of in situ generated AgCF3, it is possible to trifluoromethylate aromatictriazenes in high ortho selectivity and good yields by means of a CH substitution (see scheme). Owing to the further transformation possibilities offered by triazenes, a variety of CF3‐substituted building blocks are then accessible.
