Polarography electrosynthesis

Other electroanalytical methods The use of h.v.t. in conjunction with electroanalytical techniques of the potentiometry-polarography type has been described in detail (Kesztelyi, 1984), so that it need not be discussed here. That author, however, ignores a very useful cell for electrosynthesis under vacuum (Schmulbach and Oommen, 1973) and the electrochemical techniques developed by Szwarc and his co-workers and others in the context of anionic polymerisation, which we have mentioned above. 

Several types of electroanalytical techniques may be used to gain knowledge concerning the reaction mechanism of an electrolytic reaction and to determine the optimal conditions for an electrosynthesis. The use of classical polarography was illustrated in part I.1 The different electroanalytical techniques have been treated comprehensively in a monograph,9 and the use of... 

In some cases it is possible to use polarography to improve the yields of preparative methods, either by ascertaining the optimum conditions for organic synthesis of electrosynthesis, or by control of the isolation of natural products from biological material. 

Before embarking on an electrosynthesis it is desirable to know the potential at which the desired reaction is expected to occur. That information can be obtained from electroanalytical techniques, such as polarography and cyclic voltammetry. ... 

From 1953, much research has been done on the electrochemical behavior of CDs and their inclusion complexes. It is known that the effect of CDs on electrochemical properties of the guest molecules can be used in potentiometry, polarography and voltametry, cyclic voltammetry and amperometry. The ability of CDs to bond, orient and separate molecules and to form inclusion complexes in solution or on modified electrodes can be utilized for electrocatalysis, electrosynthesis and electroanalysis [78].

This new series contains review articles summarising, assessing and assimilating recent research on the electrochemistry of organic compounds, ranging from the kinetics of electrode processes, electrosynthesis, the effect of electrode metal on adsorption processes, electrolytic oxidation and electroreduction of organic substances to polarography.
