Introduction

Organic electrochemistry can be a very powerful synthetic tool [1, 2, 3]. Anodic oxidation as well as cathodic reduction processes are utilized [4]. If one wants to carry out a synthesis based on an anodic oxidation, the cathodic process is normally not of synthetic interest and vice versa. Nevertheless in some cases the counter-electrode process can be used also. An example is the cathodic evolution of hydrogen in protic solvents like water or methanol, while the anodic process renders the desired product. The evolving hydrogen can be utilized as fuel material. In these cases the counter-electrode reaction is of economical and not of synthetic use. But electrochemists dream of a paired electrosynthesis using cathodic and anodic process for synthesis to achieve the ultimate goal: a 200 % electrosynthesis.

There are several ways possible to perform such a paired electrosynthesis, e.g., in a parallel, convergent, divergent, or linear assembly [5, 6] (Fig. 1).
