Electrodes selection in electro-organic synthesis

The selection of electrodes is important in an electrochemical cell (divided or undivided) for organic transformations and to achieve high selectivity in product yields. Other key factors that play a role in the selection of electrodes are cost and lifetime, physical and chemical stability, non-toxicity, electrical conductivity, physical nature/form, resistance to corrosion, overpotential, and easily manipulable under electrochemical conditions. The electrode selection influences reaction efficiency and could introduce new reactivities. Catalytic electrodes are attractive in organic transformations and have many advantages such as minimal waste generation, high atom economy, and better selectivities. This article will highlight the use of different electrodes (such as Pt, C-based electrodes, Boron doped diamond, stainless steel, sacrificial, Cu, Ni.) in organic transformations with their potential applications and limitations. This article will provide information on the selection of electrodes to drive electrochemical organic transformations in a green and sustainable way.
