# Photoredox-catalyzed arylation of isonitriles by diaryliodonium salts towards benzamides

## TL;DR

This paper introduces a new method for making benzamides using light-driven reactions with isonitriles and diaryliodonium salts.

## Contribution

The first reported use of photoredox catalysis for arylation of isonitriles with diaryliodonium salts to form benzamides.

## Key findings

- Arylation of isonitriles using diaryliodonium salts under photoredox conditions produces benzamides.
- The method works with both symmetric and unsymmetric diaryliodonium salts under mild conditions.
- A plausible reaction mechanism and selectivity in aryl transfer were investigated.

## Abstract

The arylation of isonitriles by diaryliodonium salts under photoredox conditions has been proposed for the first time. The suggested procedure allows preparing a broad range of benzamides using both symmetric and unsymmetric diaryliodonium salts under mild conditions. A plausible mechanism for the reaction and the selectivity of aryl transfer (in case of unsymmetrical iodonium salts) were studied.
