Mimicking the Active Sites of Non-heme Iron Oxygenases on the Solid Supports of Catalysts: Formation of Immobilized Iron Complexes with Imidazolyl and Carboxylate Ligands

Abstract

Abstract Iron oxygenases mimicking active sites have been constructed on the solid support by anchoring a bis(imidazolyl)borate ligand to carboxylate-functionalized SBA-15 type mesoporous silica gels. Initial loading amounts of an organocarboxylic acid modifier on the silicates affect the hydrocarbon oxygenation catalyses with H2O2 due to changing of the structures of the surface metallocomplex active sites.
