In acetic acid buffer solution(pH=7.8), an adsorption-driven reduction peak of idinonine is obtained with the peak potential at -1.150V(vs.SCE), the electrode process involves single electron transfer reaction with α=0.834 and K_S=2.26 s~-1. The mechanism of the reaction is discussed simply.
The mechanism of generating superoxide radicals(O -· 2)from oxygen in alkaline aqueous solution of Na 2S 2O 4 was studied. The spetrtrum determination of ESR and UV implied a single electron transfer from SO -· 2 anion radicals to molecular oxygen.
The proton participated in the electrode process of captopril in acidic solution with one electron transfer on electrode surface to form univalent mercury-sulfur compound. The univalent mercury-sulfur compound has strong adsorptive effect on the electrode surface and transfers gradually to divalent mercury-sulfur compound.
The electrochemical reduction of N-propyl-N-butyryl-o-chloroaniline at-2.82 V has been shown to be an one-electron transfer process forming an unstable radical anion with an Odd electron at σ_(C-Cl)~* bond.
In 0.1mol/L phosphate buffer solution (pH 3.0), the voltammetry behaviors of curcumin at a glassy carbon electrode have been studied. One pair of current peaks of the voltammogram may be attributed to a reversible one-electron transfer of curcumin molecules at the glassy carbon electrode.
The electron spin densities of radical cations of chlorobenzene were calculated by an UAM1 method, and it was found that the electron spin density distribution of chlorobenzene radical cations were changed by transition-metal cations. Regioselectivities of nitration of chlorobenzene on solid acid catalysts were elucidated in terms of one-electron transfer nitration mechanism.
Kinetic studies on the single electron transfer reaction between 2, 2, 6, 6-tetramethylpiperidine oxoammonium ions and phenothia
Through analyzing the reaction properties of ANTH and CIO2, the possible pathway for the ANTH-CIO2 reaction was proposed based on the theory of single electron transfer (SET).
Above results were explained with reduction and single electron transfer reaction respectively.
These oxygenation reactions are initiated by single electron transfer between photoexcited 4-Arylmethylene-1,3(2H,4H)-isoquinolinediones and TEA, and proceeded via the anion radicals of the substrates.
This suggests that the hydrogen abstraction mechanism commonly invoked for these reaction may compete with a single electron transfer and an addition of the nitrate radical to the aromatic compound in the rate-determining first reaction step.
The formal potential of the heme Fe(III)/Fe(II) couple shifts negatively linearly with increased pH with a slope of -42.3 mV/pH, denoting that one electron transfer accompanies single proton transportation.
The oxidation via one electron transfer from ML to SO4?- and the triplet state of riboflavin (3RF*) has been also investigated and the rate constants for the process have been determined to be 8.0×109 and 1.4×109 L·mol-1·s-1 respectively.
The electrode reaction is reversible and diffusion controlled involving one electron transfer process.
The waves are irreversible, diffusion controlled involving one electron transfer process determined by millicoulometry.
The analytical procedure employs monitoring the kinetics of a simple one electron transfer reduction reaction of conversion of Ce4+ to Ce3+ in dilute aqueous solution in presence of sunlight.
