(μ-Peroxo)bis[pyridine(phthalocyaninato)iron(III)] as a convenient catalyst for the four-electron reduction of dioxygen

Effects of ring substituents on electrocatalytic activity of manganese phthalocyanines towards the reduction of molecular oxygen

“…Their activity towards oxygen reduction is better with dimeric species than their monomeric counterparts. This was observed with l-oxo-bridged dimer of an iron(III) phthalocyanine complex [9]. The geometry was reported [9] to be cofacial on electrodes facilitating coordination and splitting of oxygen.…”

“…This was observed with l-oxo-bridged dimer of an iron(III) phthalocyanine complex [9]. The geometry was reported [9] to be cofacial on electrodes facilitating coordination and splitting of oxygen. Generally, MPcs are efficient in alkaline solutions even though this medium poses difficulty of electrolyte decarbonation [10,11].…”

Oxidative Polymerization of Pyrrole Promoted by Four-Electron Transfer to O2: Catalysis of O2-Oxidation byμ-Oxo Dinuclear Complexes with Macrocyclic Ligands

“…On the other hand, it has been reported [44,45] that [(pc)Fe II ] is almost quantitatively oxidized by O 2 to 1 without the formation of partially reduced oxygen species such as H 2 O 2 . Indeed, our previous study on the electrochemical reduction of O 2 catalyzed by [(pc)Fe] adsorbed at an electrode surface revealed [33] that most of O 2 molecules (84%) are reduced by four electrons into H 2 O.…”

Two Novel μ‐Oxo Diiron(III) Schiff Base Complexes: X‐ray Diffraction Analyses, IR, UV‐Vis, CD spectra, Magnetic Susceptibility and Electrochemistry

“…[3][4][5][6][7][8][9] These complexes provide structure models for diiron sites in several proteins involved in oxygen storage of hemerythrin 10 and methane monooxygenase. 11 In addition, recent studies showed that these complexes could provide catalytic surfaces for the four-electron reduction of O 2 to H 2 O when they were immobilized at an electrode, [12][13][14] and be used as catalysts for alkane oxidation. [15][16][17] The µ-oxo diiron(III) complexes can be obtained by variable methods of preparation.…”
