Photo-induced weak base-catalyzed synthesis of α-haloboronates from vinylboronates and polyfluoroalkyl halides

Organoboron compounds play an important role in various fields due to the diverse transformations of C–B bonds. The introduction of easy-to-transform functional groups into organoboron compounds would greatly increase their synthetic application value. This article reports the first synthesis of sp2-α-haloboronates via an in situ α-sp3-boron radical intermediate, and proved their high synthetic application value through subsequent transformations.
