Chemistry is one of the cornerstones of our modern society. However, in order to provide the future generation with an equal or better standard of living, we must anticipate and limit the impact of human beings on the environment. This finding led to the definition of twelve principles that should help chemists to develop more sustainable protocols for the rational design of new reactions or new industrial processes through what they called ‘green chemistry’. In recent decades, for example, many efforts have been devoted to catalysis development. The impressive work devoted to this approach has led to unprecedented results, in particular in terms of efficiency, selectivity and waste (development of catalytic processes). Catalysis by transition metals can be cited as the most relevant example of such achievements. The scientific issue of the toxicity of nobletransition metals has recently been addressed by the scientific community. Thus, less toxic and more available metals have been considered, but their uses are still limited due to their reduced scope. Electrosynthesis has been known for years and can be considered as a “green” technique to promote oxy-reduction reactions. Electrosynthesis is based on the use of simple electrons as “clean” reagents to perform oxidation or reduction reactions making this technique attractive for university and industrialcommunity. Some industrial applications have been developed, for example, by Monsanto for adiponitrile synthesis (300000 tonnes per year) by acrylonitrile dimerisation. Other aspects of electrosynthesis have made it very attractive to synthetic chemists such as 1)cleanliness (metal reagents are replaced by simple electrons, thus reducing chemical waste at the end of the reaction), 2) a broad field of electroactivity ranging from -3.0 V/ENH to + 2.5 V/ENH depending on the solvent used to access a wide range of reactive species generated in situ from inert precursors in mild conditions and allowing access to many chemical transformations, 3) selectivity (possibility of selectively targeting a specific species from a mixture of reagents underpotentiostatic conditions) and control of the kinetics of the reaction (by regulating the current intensity applied to the system under galvanostatic conditions) and finally 4) the analytic aspects (cyclic voltametry allowing a priori to obtain accurate information on the potential for oxidation or reduction of the various reagentssimpliated in a reaction and subsequently the elucidation of the reaction mechanism).Despite these advantages, the extension of electrosynthesis has been confronted with several problems that have hampered its development as a common laboratory technique. In particular, the low conductivity of organic solvents requiring the use of supporting electrolytes (in general, ammoniumsquaterary or lithium salts) in combination with a polar solvent (in order to solubilise the electrolyte support) to overcome this limitation and the complex configuration linked to unconventional parameters for the synthesis chemist (nature and geometry of electrodes, adjustment of potential or intensity, geometry of the cell with 2 compartments or not divided).The absence of simple technical solutions to these disadvantages of organic electrosynthesis in particular for chemists of synthesis coupled with the scientific impression of the general electrochemy is the most useful understanding of the electrosynthesis.
