Abstract
The effect of solvent and supporting electrolyte on the mechanism of the electroreduction of has been studied using polarography. It has been found that both the solvent and the electrolyte have a strong influence on the course of the reduction process. The reduction proceeds via the free radical intermediate in systems containing large cations but leads directly to when the system contains small cations. In addition, it has been shown that the stability of the decreases with increasing basicity of the solvent. These effects have been interpreted in terms of ion pairing in the system.Keywords
