The aim of the present master thesis is to describe the synthesis of N‘-Benzyl-2,3-bipyridilium-halogenide and its general characterization. A special spotlight was put on electrochemical methods like cyclic voltammetry and spectroelectrochemistry, however other means of examination and de-scription like UV-vis-, fluorescence-, IR- and NMR-spectroscopy were also applied. The (electro-)chemical behaviour of the introduced molecule in presence of selected Rhodium catalysts, acids and especially CO2 was of interest. An important part was the redox-chemistry and its possible application, especially for electrochemical reduction of CO2. N‘-Bn-2,3-BipyCl was assumed to catalyse this reaction to achieve sustainable products such as methanol or formate. Several electrolysis experiments to reduce CO2 in presence of this compound were performed. Crucial in this electrolysis is the choice of the electrode material and the electrolyte, which may participate in this reaction. In order to exclude side-effects of these two factors, an inert working electrode and a buffered phosphate solution as an electrolyte were selected. The yield of the products in question however was low. Small amounts of formate were obtained. This agrees partly with previous work of Jean-Michel Savéant and Andrew Bocarsly. In this light the role N‘-Bn-2,3-BipyHal can be examined in further setups and so be part of a systematic list of described N-heterocyclic compounds to catalyse the electrochemical reduction of CO2.
