Electrochemically Catalyzed Decarboxylative Borylation of (Hetero)Aryl Carboxylic Acids

A straightforward and efficient electrochemical method for the decarboxylative borylation of (hetero)aryl carboxylic acids has been outlined. This metal-/base-/oxidant-free strategy enables efficient access to arylboronate esters, demonstrating a broad substrate scope (20 examples) with yields of up to 62% while maintaining exceptional atom- and step-economy.
