Unusual electrochemical oxidation of cholesterol

Steroids, 2008
It has been found that cholesterol undergoes direct electrochemical oxidation on platinum electrode in dichloromethane. Voltammetric measurements show that the process is controlled by the rate of electron transfer and the height of the oxidation peak is linear vs. concentration of cholesterol.

Electrochemical oxidation of benzyl germatranes

Journal of Organometallic Chemistry, 2008
Abstract The electrooxidation of ring-substituted bromobenzylgermatranes in CH 3 CN and DMF solutions was studied. By cyclic voltammetry supported by DFT B3LYP/6-311G calculations, donor activity of the nitrogen atom was shown to be substantially reduced because of the dative N → Ge coordination compared to Et 3 N and (HOCH 2 CH 2 ) 3 N.

Electrochemical Oxidation

Electrochemical oxidation (EO) is able to mineralize poly- and perfluoroalkyl substances (PFAS) through potential-driven electron transfer in concert with reactions with reactive species on the anode surface. Performance of EO treatment hinges on the properties of the anode materials, the target PFAS, and the electrolytes, as well as the water quality ...

Electrochemical Oxidation of Methane to Methylamine

Journal of the American Chemical Society
The electrochemical methane (CH4) oxidation reaction under ambient conditions is a promising approach for natural gas utilization. However, the highly stable nature of CH4 restrains efficient cleavage of the C-H bond without overoxidation. To this end, we proposed a coupled oxidative strategy for converting CH4 to value-added products via NH2 ...

Effect of the electrochemical oxidation/reduction cycle on the electrochemical capacitance of graphite oxide

Carbon, 2014
Abstract Reduction largely affects the properties of graphene oxide (GO), because the content of each functional group changes by the oxidation degree. So far no study about re-oxidation and re-reduction of GO has been carried out. Herein, we report the effects of oxidation/reduction cycle of graphite oxide (GtO, multilayered GO) on its composition ...

Electrochemically Induced Growth of Zinc Oxide

ChemPhysChem, 2007
AbstractThe electrolytically induced precipitation of zinc oxide from zinc nitrate solution on gold surfaces in the presence of water‐soluble polymers was examined for reaction times between 0.5 and 600 seconds. Regardless of the additive, polycrystalline films of zinc oxide have formed after 30 seconds, but polymeric additives dramatically change the ...

Electrochemical oxidation of hypoxanthine

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1981
Abstract The electrochemical oxidation of hypoxanthine (6-oxypurine) in aqueous solution has been studied. The evidence strongly supports the view that hypoxanthine is initially electrooxidized in a 2 e −2H + reaction to give 6,8-dioxypurine. The latter compound is more easily oxidized than hypoxanthine and is immediately further electrooxidized to ...

Electrochemical oxidation of methylindoles

Collection of Czechoslovak Chemical Communications, 1981
Electrochemical oxidation of 1-methylindole (I), 1,3-dimethylindole (II) and 1,2-dimethylindole (III) on a platinum anode in methanol, containing ammonium bromide, was studied. A more profound oxidation as compared with benzofuran or benzothiophene derivatives is indicated by the obtained products: 1-methyl-2,2-bis(1-methylindol-3-yl)-3-indolinone (IV),

Electrochemical oxidation of zopiclone

Monatshefte für Chemie - Chemical Monthly, 2015
Electrochemical behaviour of zopiclone was investigated on glassy carbon electrode in static and rotation disc arrangement. Strong influence of kinetics and adsorption phenomena on the electrode processes was proved by voltammetric techniques. Controlled potential electrolysis in off-line and on-line combination with tandem mass spectrometry was ...
