Photocatalyzed Arylation of Isonitriles by Diaryliodonium Salts towards N-Substituted Benzamides

The arylation of isonitriles by diaryliodonium salts under photoredox conditions has been proposed for the first time. The suggested procedure allows preparing the broad range of N-substituted arylamides using both symmetric and unsymmetric diaryliodonium salts in mild conditions. The plausible mechanism for the reaction and the selectivity of aryl transfer in case of asymmetrical iodonium salts was studied.
