Abstract

A series of diiron(III) complexes of 1,3-bis(2′-arylimino) isoindoline, [(Fe(L)Cl)2O] and 1,4-di-(2′-aryl) aminophthalazine, [Fe2(μ-OMe)2(H2L)Cl 4], including new structurally characterized ligands, 1,4-di-(4′-methyl-2′-thiazolyl)aminophthalazine and 1,4-di-(2′-benzthiazolyl)-aminophthalazine, have been characterized, and used as catalysts for the oxidation of para-substituted phenyl methyl sulfides and benzyl alcohols. Hammett correlations and kinetic isotope effect experiments support the involvement of electrophilic metal-based oxidants. In case of [(Fe(L1,2)Cl)2O] catalysts, direct correlation has been found between the oxidative and catalase-like activity.
