An unprecedented silver‐catalyzed formal insertion of arynes into RfI (Rf=CF3, C2F5) bonds has been developed. This protocol provides easy access to various ortho‐perfluoroalkyl iodoarenes under mild conditions. In this insertion reaction, an ionic atom‐transfer reaction of RfI occurs, and a silver‐mediated metathesis process is involved in the efficient transfer of the electropositive iodine atom

An unprecedented silver-mediated vicinal trifluoromethylation-iodination of arynes that quickly introduces CF3 and I groups onto aromatic rings in a single step to give o-trifluoromethyl iodoarenes has been developed. A new reactivity of AgCF3 has been revealed, and 2,2,6,6-tetramethylpiperidine plays an important role in this difunctionalization reaction.
