“…FeCl 3 has been used previously as an oxidant for porphyrins − and is also a promising candidate for the dimerization of the BODIPY compounds. , Electrochemistry can also be used for the coupling reactions. − Its advantage compared with the chemical methods is the more precise control of the oxidation potentials necessary to achieve coupling, with the potential of obtaining a higher yield of the product and lack of formation of products of the oxidant. Electrochemical dimerization by oxidative and reductive coupling reactions has been widely studied. − For example, electrohydrodimerization of activated olefins, most importantly acrylonitrile, by the hydrodimerization process is of importance as a commercial process for the production of the adiponitrile. − Numerous studies have been carried out to elucidate the dimerization mechanism and determine kinetic parameters for the reactions by using cyclic voltammetry (CV), − ,− scanning electrochemical microscopy, , electron spin resonance, − and ECL. − …”
