N‑Acylimino‑λ3‑iodanes from the Metathesis of Iodosoarenes and Nitriles for the Photoinduced C–H Perfluoroacylamination of (Hetero)Arenes

An efficient and scalable synthesis of N-perfluoroacylimino-λ3-iodanes was achieved via an unprecedented metathesis between iodosoarenes and perfluoroalkanenitriles. The perfluoroacylamino groups of the iodanes could be introduced to aromatic and heteroaromatic rings using photoirradiation.
