electrochemical C(sp2)−C(sp3) cross‐coupling reaction of bench‐stable aryl halides or β‐bromostyrene (electrophiles) and benzylic trifluoroborates (nucleophiles) using nonprecious, bench‐stable NiCl2⋅glyme/polypyridine catalysts in an undivided cell configuration under ambient conditions. The broad reaction scope and good yields of the Ni‐catalyzed electrochemical coupling reactions were confirmed by

Mg for B: An atom‐economical one‐potsynthesis by direct magnesium insertion in the presence of B(OBu)3 and LiCl allows a broad range of functionalized (hetero)aryl and alkenyl bromides to be converted into magnesium diorganoboronates 2, which undergo Suzuki–Miyauracross‐couplingreactions with various aryl (pseudo)halides (see scheme). Both aryl groups of 2 are transferred and furnish the products
