RECENT DEVELOPMENTS WITH ORGANIC ELECTROS YNTHESIS TECHNIQUES

Recent developments of some electro-organic processes of industrial in terest studied in France are presented. They are illustrated by exampl es of syntheses conducted by classical oxidation or reduction of chemi cal functions. Special attention is payed to the use of cathodes activ ated in situ by a zinc layer and their application in the electrosynth eses of chlorotrifluoroethylene and amino-alcohols. New reactors with porous electrodes are particularly suitable for the syntheses of a cer tain number of nitroso-compounds. Electrochemical processes involving the use of sacrificial anodes of magnesium, or aluminum, which are int eresting in functionalization of organic halides, were particularly de veloped in France these 10 last years. Examples concerning the build-u p of new materials such as doped polymers, or some organosilanes used as ceramic precursors are also presented. Some of the above cases cons titute favorable occasions to discuss innovations in electrochemical r eactor technology.
