Ortho‐Trifluoromethylation of Functionalized Aromatic Triazenes

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