Review of Electrochemical Syntheses of Aroma Chemicals

Electrochemical syntheses of organic chemicals become more and more important as simple and effective ways of preparing fragrance and flavour raw materials. The main advantages of these methods are:

—simplicity of technology —reaction selectivity —low pollution and wastes —possible process-automation —simple equipment and reaction conditions —possible regeneration of materials —unique chemistry of some of the reactions.

There are several literature references on practical industrial applications of electrochemical methods in the syntheses of some chemicals. The examples given in Table I show syntheses of aroma chemical and intermediates, The range and variety of products manufactured by fragrance and flavour chemistry create interesting possibilities for introduction of electrochemical syntheses. In this review we collected data from available literature and our own experiments to show nearly unlimited possible applications of electrochemical methods in our industry.
