An electrocatalytic oxidation enables the construction of various (E)-vinyl sulfones directly from cinnamic acids and sodium sulfinates with high regioselectivity at room temperature via a sulfonyl radical intermediate.

A thiazolium precatalyst facilitates electrochemical oxidation of thiolate anions, leading to deleterious formation of disulfide byproducts. For the reaction of a broad range of aldehyde and thiol substrates, thioesters were obtained in very good yields . This approach provides an atom-efficient thioesterification that circumvents the need for stoichiometric exogenous oxidants, high cell potentials, or redox mediators.

Direct electrolysis of primary alcohols  leads smoothly to the formation of the corresponding deoxygenated product in high yield in the presence of methyl toluate.
K. Lam, I. E. Mark§, Synlett, 2012, 23, 1235-1239.


Electrolysis using an undivided cell fitted with a pair of zinc electrodes in a mixture of saturated aqueous NH4Br and tetrahydrofuran enables an efficient synthesis of alkenes from epoxides. The reaction is mediated by Zn(0) with a hierarchically organized nanostructure.

An electrochemical reduction of diphenylphosphinate esters leads smoothly and in high yields to the corresponding deoxygenated products. The electrolysis could be performed at low temperature and with a high current density, resulting in a short reaction time.
