Progress in the Electrochemical Synthesis of Organoboron Compounds

Organoboron is a class of compounds widely used in organic synthesis, pharmaceuticals, material science, sensors, and so on. Therefore, the development of efficient and selective electrochemical methods to synthesize organoboron has attracted much interest as an emerging sustainable technique of organic synthesis. Here, we summarized research on electrochemical borylations, including the electrochemically driven borylation of arenes, alkanes, aryl, or alkyl halides, activated carboxylic acids etc., based on direct electrolysis and metal-free organocatalysis. We focus on the reaction mechanisms involved in single-electron transfer and other radical processes. We believe that this review will inspire electrochemists to discover more efficient transformations to expand this field of borylation.
