A wide variety of ligands from didentate to pentadentate as well as dinucleating ligands have been designed and synthesized for modeling the active site of iron and manganese enzymes exhibiting a catalytic function. Relevant iron and manganese complexes of these ligands together with their catalytic activity in the oxidation of hydrocarbons will be discussed in the next sections. III. Biomimetic Iron Catalysts A. 1. Mononuclear Iron Complexes A large number of mononuclear iron(II) complexes with polydentate ligands (Fig.
