Carbon–heteroatom bonds represent omnipresent structural motifs of the vast majority of functionalized materials and bioactive compounds. C−H activation has emerged as arguably the most efficient strategy to construct C−Het bonds. Despite of major advances, these C−H transformations were largely dominated by precious transition metal catalysts, in combination with stoichiometric, toxic metal oxidants. Herein, we discuss the recent evolution of cobalt‐catalyzed C−H activations that enable C−Het formations with electricity as the sole sustainable oxidant until May 2018. The recent merger of cobalt‐catalyzed C−H activation with electrosynthesis has enabled C−Het and C−Het formations with electricity as the sustainable oxidant.
