Modern Electrochemical Aspects for the Synthesis of Value‐Added Organic Products

Abstract

The use of electricity instead of stoichiometric amounts of oxidizers or reducing agents in synthesis is very appealing for economic and ecological reasons, and represents a major driving force for research efforts in this area. To use electron transfer at the electrode for a successful transformation in organic synthesis, the intermediate radical (cation/anion) has to be stabilized. Its combination with other approaches in organic chemistry or concepts of contemporary synthesis allows the establishment of powerful synthetic methods. The aim in the 21st Century will be to use as little fossil carbon as possible and, for this reason, the use of renewable sources is becoming increasingly important. The direct conversion of renewables, which have previously mainly been incinerated, is of increasing interest. This Review surveys many of the recent seminal important developments which will determine the future of this dynamic emerging field.

Tapping Renewables: A New Dawn for Organic Electrosynthesis in Aqueous Reaction Media

“…This development was mainly driven by the fascination on and elegancy of the possible electroorganic reactions. The manifold portfolio of electroorganic reactions and reaction mechanisms in non‐aqueous solvents including, e. g., methanol, ethanol, acetonitrile and THF is reported, e. g., in . During the same period, organic electrosynthesis in aqueous reaction media were investigated, too, but to a far lesser extent.…”

“…The elucidation of the mechanisms of organic electrosyntheses in aqueous reaction media, the discovery of new and the rediscovery of previously described syntheses for a biobased economy will be a vital and rewarding field of research for the next decades . In addition, engineering organic electrosyntheses will be of equal importance in order to implement these in the chemical industry .…”
