molecules. Because arylacetic acids are regarded as key structures in bioactive compounds, new transformations of these structures could contribute to drug/agrochemical discovery and chemical biology. This work reports carbon–nitrogen and carbon–oxygen bond formation through the photoredox‐catalyzed decarboxylation of arylacetic acids. The reaction shows good functional group compatibility without pre‐activation

A new synthetic approach toward intermolecular oxidative C-N bond formation of arenes has been developed under transition-metal-free conditions. Complete control of chemoselectivity between aryl sp(2) and benzylic sp(3) C-H bond imidation was achieved by the choice of nitrogen sources, representatively being phthalimide and dibenzenesulfonimide, respectively.
