Electrosynthesis

Organic reductions or organic oxidations or organic redox reactions are redox reactions that take place with organic compounds. In organic chemistry oxidations and reductions are different from ordinary redox reactions because many reactions carry the name but do not actually involve electron transfer in the electrochemical sense of the word.

The Importance of Acid–Base Equilibria in Bicarbonate

2021/4/29In this study, we assess the structure and electrolyte dependence of CO2RR on monocrystalline Au(hkl) electrodes.Based on the ability of the gold electrode to selectively oxidize CO, we detect the CO produced during CO2RR by applying anodic potentials.(28) In this way, we gain insights into the selectivity-potential trend for CO2RR in bicarbonate electrolyte through a fast semiquantitative

Electrochemical approaches to the direct arylation of carbonyls and alcohols through less‐explored cathodic reduction and convergent paired electrolysis are presented. This protocol features: excellent functional group (including ester, amide, amine, thioether, borate) tolerance, mild conditions (metal catalyst‐ and external reductant‐free), good scalability (10 gram‐scale), and site

Molecules

The electrochemical half-reactions are ideally both benefitted from, to afford valuable products at both electrodes (paired electrolysis). This implies that photoredox catalysis is ideal for conducting redox-neutral transformations due to the homogeneous presence and transient nature of the redox-active excited photocatalyst and complementary oxidized/reduced state.
