Cyclic Voltammetry of Auranofin

The oxidative behavior of Auranofin, 2,3,4,6-tetra-O-acetyl-1-thio-beta-D-glucopyranosato- S(triethylphosphine)gold(I), was investigated by using cyclic voltammetry (CV) in 0.1 M Bu(4)NPF(6)/CH(2)Cl(2) and 0.1 M Bu(4)NPF(4)/CH(2)Cl(2) solutions using Pt working and auxiliary electrodes and a Ag/AgCI reference. CV studies at scan rates from 50-2,000 mV/s and Auranofin concentrations between 1 an...

Variable scan rate cyclic voltammetry and theoretical studies on tocopherol (vitamin E) model compounds.

Variable scan rate (0.1-500 V s(-1)) cyclic voltammetry experiments were performed on a series of model tocopherol (vitamin E) compounds with differing degrees of methyl substitution around the aromatic (phenolic) ring. alpha-Tocopherol, with a fully methylated aromatic ring, produced stable phenoxonium cations upon oxidation in CH3CN, and was modeled via an ECE mechanism (where "E" represents ...

Cyclic voltammetry and XPS studies of monolayers deposited on gold and platinum electrodes displaced by mercaptopyridines

We present studies, by cyclic voltannnetry and X-ray photoelectron specu'oscopy (XPS), of the under and oveq~otenfial deposition of copper on polycrystalline platinum and gold electrodes in aqueous 0.50 M sulfuric acid solution in the presence and absence of ads(~r~d layers of 2and 4-mereaptopyridine (2-MP, 4°MP). in general we find that the presence of adsorbed htyers of either 2-MP {~r 4-MP g...

Study on Electrochemical Oxidation of m-Nitrophenol on Various Electrodes Using Cyclic Voltammetry

The electrochemical oxidation behavior of m-nitrophenol (m-NP) was studied comparatively on glassy carbon electrode, Pt electrode, PbO2 electrode, SnO2 electrode, and graphite electrode using cyclic voltammetry. The cyclic voltammetry measurements were performed in acidic (1 M H2SO4, pH 0.4), neutral (1 M Na2SO4, pH 6.8), and...
