Electron-Transfer Properties of Cp*FeP5: Evidence for Dimerization Reactions following both Oxidation and Reduction
The redox reactions of Cp*Fe(η-P5) (1; Cp* ) η-C5Me5) have been characterized in nonaqueous solvents by electrochemical methods. As anticipated by analogy with ferrocene, 1 may be both oxidized and reduced in one-electron processes. Both processes are irreversible by cyclic voltammetry but reversible by bulk electrolysis. In CH2Cl2 complex 1 oxidizes initially to 17-electron 1+ (Ep,a ) 0.57 V v...

متن کاملThe Electrocatalysis of Ethanol Oxidation
In this paper, the main characteristics of ethanol electrooxidation are presented and the results of electrochemical and spectroscopic methods are discussed. The total oxidation reaction should produce 12 e/molecule. However, on Pt catalysts, the reaction follows parallel pathways forming acetaldehyde, acetic acid and carbon dioxide as soluble products. Thus much lower yields of charge per etha...
متن کاملOxidation-reduction reactions of metal ions.
Several metal or metalloid ions exist in multiple oxidation states and can undergo electron transfer reactions that are important in biological and environmental systems. There are endogenous metal ions such as iron, copper, and cobalt that participate in oxidation-reduction reactions with species of oxygen like molecular dioxygen, superoxide, and hydrogen peroxide. These reactions may be modul...
متن کاملPhotochemical Reduction and Oxidation Reactions on Barium Titanate Surfaces
The influence of the ferroelectric domain structure of BaTiO3 on the photochemical reactions that occur on its surface has been examined using atomic force microscopy. Both the photochemical reduction of aqueous silver cations and the oxidation of steric acid thin films were studied. During reduction, silver selectively deposits on the surface in patterns determined by the ferroelectric domain ...
