Electrochemical oxidation of nitroylides

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1981
The mechanisms of the electrochemical oxidation of mono- and dinitroylides of S and Se on a Pt electrode in CH3CN have been studied for the first time. It was shown that the cation radical formed as intermediate was able to react with the medium with removal of an H atom and with the formation of an onium cation or to undergo decomposition.

Electrochemical oxidation of acylsilanes

Tetrahedron Letters, 1989
Abstract Oxidation potentials of acylsilanes were found to be much less than those of the corresponding ketones and aldehydes. Electrochemical oxidation of acylsilanes resulted in facile cleavage of the carbon-silicon bond and introduction of oxygen and nitrogen nucleophiles at the carbonyl carbon.

Electrochemical oxidation of tryptophan

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1986
Abstract The electrochemical oxidation of tryptophan at graphite electrodes has been studied in aqueous solutions over a wide pH range. The single voltammetric oxidation peak of tryptophan is due to an irreversible 2 e− reaction giving an extremely reactive methylene-imine intermediate.

Electrochemical oxidation of thiobenzanilide

Electroanalysis, 1994
AbstractThe electrochemical oxidation of thiobenzanilide was studied in anhydrous acetonitrile as a model for the enzymatic oxidation of the substance. It has been found that a single electron is exchanged in the presence of 5 × 10−2 M HClO4 The oxidation products were identified as H2S, benzanilide, and 2‐phenylbenzthiazole.

Electrochemical Oxidation of Tolterodine

Electroanalysis, 2012
AbstractThe electrochemical behavior of tolterodine, an antimuscarinic drug used to treat urge incontinence and overactive bladder, was investigated using cyclic and differential pulse voltammetry at glassy carbon electrode. Electrooxidation of tolterodine proceeds as a complex two‐step pH‐dependent process.

Electrochemical Oxidation of Phenol

Journal of The Electrochemical Society, 1986
The electrochemical oxidation of phenol was studied using a packed bed reactor of pellets with recirculating anolyte in order to follow phenol loss and benzoquinone, maleic acid, and carbon dioxide formation. A carbon mass balance revealed a significant fraction of additional by‐products for initial phenol concentrations of ≥ 0.014M.

Electrochemical oxidation of rhenium

Corrosion Science, 1973
Abstract The anodic oxidation of rhenium in aqueous medium was studied in applying the potentiodynamic and galvanostatic methods. The polarization curves I = ƒ(V) do not show any irregular features up to the highest current densities reached (50 mA.cm −2 ).

Electrochemical oxidation of ketoximes

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1989
The oxidation of ketoximes on a platinum anode in acetonitrile proceeds through the intermediate formation of the corresponding radical-cation, iminoxyl radical, and oxoimmonium cation.

Electrochemical oxidation and reduction [PDF]

, 1974
The electrode reactions which occur when a solution of an ionic solute is electrolyzed involve the gain of electrons by an ion at the cathode, and the loss of electrons by an ion at the anode. The primary electrode reactions can be represented by the ionic equations This allows the generalization that oxidation occurs at the anode and reduction

Electrochemical Oxidation of Hydrocarbons

Berichte der Bunsengesellschaft für physikalische Chemie, 1964
AbstractFuel cell oxidation is described for some of the gaseous hydrocarbons, and for methanol and formic acid, electrolyte‐soluble fuels. Cell construction for both systems was similar, in that inorganic vehicles were employed to partially immobilize the acid electrolytes.
