Atomic carbon and its corresponding masked analogues are exceedingly underexplored intermediates in synthesis. Despite this, these reagents possess inimitable reactivity such as the ability to directly insert carbon atoms into aromatic frameworks while simultaneously generating an additional bond at the carbon center to further diversify the structure. Herein, we report the design of the orthogonally

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
