in situ in the reductive activation of dioxygen by an iron(II)–benzilate complex of a monoanionic facial N3 ligand, promoted the halogenation of aliphatic C−H bonds in the presence of a protic acid and a halideanion. An electrophilic iron(IV)–oxo oxidant with a coordinated halide is proposed as the active oxidant. The halogenation reaction with dioxygen and the iron complex mimics the activity of non‐heme

nonheme halogenases catalyze the halogenation of aliphatic C–H bonds in the biosynthesis pathway of many natural products. An iron(IV)-oxo-halo species has been established as the active oxidant in the halogenation reactions. With an objective to emulate the function of the nonheme halogenases, two iron(II)-α-keto acid complexes, [(phdpa)Fe(BF)Cl] (1) and [(1,4-tpbd)Fe2(BF)2Cl2] (2) (where phdpa = N
