Metal‐Free Electrochemical Hydroboration of Olefins

Abstract Herein, we reported the electrochemical hydroboration of olefins to access the organoboron derivatives in a one‐pot reaction under air and at room temperature. This reaction manifold was applied to a broad range of alkenes with 40–90% yields and good functional group tolerance without using a metal catalyst or an additional hydride source. Mechanistic studies suggested that this anodic oxidation conducted in an undivided cell allowing the production of a boron radical species, which initiates the hydroboration of olefins event by a radical addition process.
