Decarboxylative Borylation: New Avenues for the Preparation of Organoboron Compounds

The preparation of organoboron compounds has been widely explored and persistently pursued in organic chemistry. Recently, redox‐activated N‐hydroxyphthalimide carboxylic esters have been utilized as efficient feedstocks for decarboxylative borylation processes, enabling coupling between the abundant carboxylic acids and the versatile organoboron compounds. Here we highlight such advances, with an emphasis on clarifying the different working mechanisms for Ni‐catalyzed, light‐promoted, or organocatalytic decarboxylative borylative reactions.
