A wide variety of mixed anhydrides formed in situ from carboxylic acids and acyl chlorides can subsequently undergo metal insertion-decarboxylation-recombination to provide ketones in very good yield when subjected to metallaphotoredox catalysis. A three-step synthesis of the medicinal agent edivoxetine is also described.
