The aim of this project is to develop electrocatalytic methods for enantioselective chemical bond forming reactions based on a mechanistic understanding of the one-electron redox chemistry. We will seek to understand the recently described terpyridine-based nickel complexes under catalytically relevant conditions by electrochemical and spectroelectrochemical methods (EPR and UV/vis/NIR) and get thus insight into the catalytic mechanisms. Based on this we want to design new ligands for redox-triggered enantioselective cross-coupling reactions. Furthermore we would like to extend the application of nickel based cross coupling reaction to further substrates and thus develop the preparative electrocatalytic cross-coupling reactions.

本项目的目的是基于对单电子氧化还原化学的机理理解，开发对映选择性化学键形成反应的电催化方法。我们将试图通过电化学和光谱电化学方法（EPR和UV/vis/NIR）了解最近描述的在催化相关条件下的三吡啶基镍配合物，从而深入了解催化机理。在此基础上，我们想为氧化还原触发的对映选择性交叉偶联反应设计新的配体。此外，我们希望将镍基交叉偶联反应的应用扩展到其他底物上，从而发展制备性电催化交叉偶联反应。
