Non‐Heme‐Iron‐Mediated Selective Halogenation of Unactivated Carbon−Hydrogen Bonds

Oxidation of the iron(II) precursor [(L 1 )Fe II Cl 2 ], where L 1 is a tetradentate bispidine, with soluble iodosylbenzene ( s PhIO) leads to the extremely reactive ferryl oxidant [(L 1 )(Cl)Fe IV =O] + with a cis disposition of the chlorido and oxido coligands, as observed in non‐heme halogenase enzymes. Experimental data indicate that, with cyclohexane as substrate, there is selective formation of chlorocyclohexane, the halogenation being...
