Molecular electrochemistry

One focus of the thematic group is the development of electrochemical syntheses of organic compounds. Our extensive equipment and expertise allow us to adapt the experimental setup and the type of reaction control to a variety of different synthetic challenges. Thus, divided and undivided cells are used as required, which can be operated in potentiostatic or galvanostatic mode. If necessary, the preparative work is supplemented by electroanalytical studies, which provide both mechanistic insights and information that is useful for the optimization of reaction parameters. As a further tool, we use homogeneous electrocatalysts (mediators) or catalytically active electrode materials if required. This approach allows both selectivity control and lowering of the kinetic overpotential. To accelerate optimization, screening setups are used that allow up to eight electrolyses to be carried out simultaneously per apparatus. For up-scaling of the reaction, various flow cells are available, which can be coupled with different analytical methods for online product analysis.
