[Fe(Ligand)_x]²⁺ complexes immobilized into montmorillonite ([Fe(Ligand)_x]²⁺@Mont, Ligand: 2,2′;6′,2′'-terpyridine (x = 2), 1,10-phenanthroline (x = 3), and 2,2′-bipyridine (x = 3)) were prepared by an ion-exchange method whereby cations present within montmorillonite (probably Ca²⁺) were replaced by [Fe(Ligand)_x]²⁺ complexes provided by [Fe(Ligand)_x](ClO₄)₂. The catalytic properties of the species obtained were then investigated in the oxidation of cyclic hydrocarbons, such as cyclohexane and benzene, with H₂O₂. The catalytic oxidation of cyclohexane and benzene with H₂O₂ over [Fe(Ligand)_x]²⁺@Mont catalysts proceeded, and the desired alcohols were obtained as the main reaction products, whereas no catalytic activity was displayed by neat montmorillonite. Regardless of the reaction conditions, [Fe(terpy)₂]²⁺@Mont (terpy stands for 2,2′;6′,2′'-terpyridine) exhibited the best catalytic performance in the oxidation of the mentioned substrates by H₂O₂, among all the catalysts tested.
