The Fixation with Fixation: Chemical Transformations of Dinitrogen

The fixation of dinitrogen to ammonia provides the nitrogen feedstock for the nutrition of about half of earth’s population and for the production of basically all synthetic N-containing chemicals. The Haber-Bosch process that operates at about 200 Mio tons p.a. is highly energy intensive, consuming about 1–2 % of the global energy demand. For these reasons, N2 fixation at ambient conditions, which is accomplished in nature by the nitrogenase enzymes, is a highly attractive, yet still challenging task for homogeneous catalysis.

In recent years, our group examined elementary reactions relevant to such N2-fixation strategies, such as nitride hydrogenolysis and coupling,[1,2] thermal and electrochemical N2 splitting into molecular nitrides,[3] or the direct conversion of N2 to organic molecules (Figure),[4] using transition metal pincer complexes. In this context, mechanistic aspects of key reactions and electronic structure/reactivity relationships for pivotal intermediates will be discussed.
