Role of protonation and of axial ligands in the reductive dechlorination of alkyl chlorides by vitamin B12 complexes. Reductive cleavage of chloroacetonitrile by Co(I) cobalamins and cobinamides.
TL;DR: Cobalt(I) cobalamin and cobinamide are efficient catalysts of the hydrogenolysis of aliphatic chloro compounds, and experiments carried out in DMF with addition of an acid show that a crucial step in the catalytic process is the proton transfer decomposition of the alkylcobalt (II) complex, leading to the product, and closing the catalysttic loop by regeneration of the cobalt( I) complex.

Cyclic voltammetry with asymmetrical potential scan: A simple approach to mechanisms involving moderately fast chemical reactions
TL;DR: In this paper, the use of trapezoidal and triangular potential-scan methods to the mechanistic analysis of chemical reactions coupled with electron transfer is investigated. But the method is particularly suited to the study of mechanisms involving chemical reactions following the charge transfer or interposed between two consecutive charge transfers, and it is shown that very asymmetric potential scan leads to very simple analysis criteria for characterizing qualitatively and quantitatively the rate determining chemical step.

Evidence for Concerted Proton−Electron Transfer in the Electrochemical Oxidation of Phenols with Water As Proton Acceptor. Tri-tert-butylphenol.
TL;DR: The cyclic voltammetric observation of the electrochemical oxidation and reverse reaction has allowed the clear identification of a pathway in which a phenol is directly and reversibly converted into the phenoxyl radical while the generated proton is accepted by a water molecule in a concerted manner.

Stepwise and concerted electron-transfer/bond breaking reactions. solvent control of the existence of unstable pi ion radicals and of the activation barriers of their heterolytic cleavage.
TL;DR: A simple model system involving the anion radical of ONCH(2)Cl and two molecules of water is examined, which allows the application of advanced computational techniques and a treatment of these solvent effects that emphasizes the role of solvent molecules that sit close to the charge centers of the molecule.
