-Acylimino-λ-iodanes from the Metathesis of Iodosoarenes and Nitriles for the Photoinduced C-H Perfluoroacylamination of (Hetero)Arenes.

An efficient and scalable synthesis of -perfluoroacylimino-λ-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.
