Electrochemical oxidation of xanthosine

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1987
Abstract The electrochemical oxidation of xanthosine in aqueous solution at pH 2.0 at the pyrolytic graphite electrode has been studied. The primary electrochemical oxidation reaction is an irreversible 1 e−, 1 H+ reaction giving the C(8) free radical.

Electrochemical oxidation of aldoximes

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1989
The electrochemical oxidation of aldoximes was found to proceed with the loss of one electron and formation of the corresponding iminoxyl radical, which undergoes subsequent chemical reactions more rapidly than undergoing oxidation on the electrode.

Electrochemical oxidation of sulphacetamide

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1988
Abstract The electrochemical oxidation of sulphacetamide (I) at a pyrolytic graphite electrode has been examined in the pH range 2.2–9.9 by linear and cyclic sweep voltammetric, coulometric and spectral studies. The 2 e − , 2 H + oxidation of this compound in controlled potential electrolysis gives an azo (IV) and a hydroxylamino compound (V) as ...

The electrochemical oxidation of phenylenediamines

Electrochimica Acta, 2009
Abstract Five p-phenylenediamines were oxidized electrochemically at a glassy carbon rotating ring-disk-electrode assembly. The overall reaction comprises the transfer of two electrons per molecule. At low to intermediate potentials the rate determining step for all the five compounds is the acid dissociation of the semiquinonediimine radical cation ...

Electrochemical Oxidation of Benzylsilanes

1997
Electrochemical oxidation of substituted trialkylbenzylsilanes follows the ECE scheme including reversible electron transfer and formation of a short-lived radical cation, which can be detected for methoxybenzylsilanes at high sweep rates. In terms of the three-parameter model of the electrochemical reactivity of benzylsilanes, the inductive effect of ...

Electrochemical oxidation of aryldisilanes

2000
Oxidation of disilanes containing at least one aromatic substituent at the silicon atom involves reversible electron transfer with formation of radical cations of different stabilities. The subsequent transformations of the radical cations are governed by the possibility of charge delocalization over the developed HOMO and the presence of a good ...

Electrochemical oxidation of hexaalkyldisilanes

1999
Electrochemical oxidation of hexaalkyldisilanes in acetonitrile follows the activation mechanism with cleavage of the Si-Si bond in the overall two-electron process. Oxidation of hexamethyldisilane occurs at a potential 1 V more positive than the standard potential of the process. The standard potential of the leaving group Me3Si+/Me3Si is negative and
