Abstract:
Electrohydrodimerization (EHD) of fumarodinitrile (FDN)on Gallium takes place not only from hydrotropic solutions of tetraethylammonium p toluenesulphonate (TEA PTS),but also from entrirely aqueous solution containing very low concentrations (say 10-1~10-3 mol·L-1) of strong surfactants,such as TritonX 100.In aqueous solution,not containing organic surfactants,FDN yields a single two electron reduction wave to the corresponding saturated (RH 2).Progressive additions of surfactants,the original two electron wave is splitted into two consecutire single electron reduction wave and the EHD of fumarodinitrile is obtained.
