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

Oxidizing a first aromatic compound in the presence of a metal salt to yield a second aromatic compound includes combining the first aromatic compound, the metal salt, and water to yield an aqueous mixture, and heating the aqueous mixture at a temperature exceeding 200° C. to yield a reaction product that includes the second aromatic compound.
