报告摘要

The direct use of N₂ for the synthesis of nitrogenous organic products, such as amines, nitriles, or nitro compounds, is still challenging and catalytic protocols remain unknown. The reductive splitting of dinitrogen into transition metal nitrido complexes represents a potential entry towards N₂ fixation beyond ammonia.^[1] Over the past years, our group examined the mechanisms of chemically, photochemically, and electrochemically driven reductive N2 splitting by group 6 and 7 metal complexes as a starting for the transformation of dinitrogen to nitrogenous products, like organic nitriles (see Figure).^[2]

In this presentation, the mechanistic and electronic structure prerequisites for electro- and photochemically driven reductive N₂ splitting that is mediated by molecular pincer complexes will be presented, as well as strategies for efficient nitrogen transfer to target molecules.
