气态氮（N2）的还原对于工业、生物和合成化学家来说是一个挑战，他们希望了解农业用氨（NH3）的形成，也希望形成精细化学合成的N-C和N-Si键。固氮酶的铁钼活性位点激发了化学家探索铁和钼络合物带来与N2还原相关的转化的能力。这一研究领域已经获得了显著的发展势头，过去两年在合成Fe-N2和Mo-N2化学方面取得了许多重大进展。此外，固氮酶的铁钼辅因子中所有原子的身份终于得到了阐明，碳化物的发现为配位化学家带来了新的问题和目标。本文总结了铁和十二指肠络合物的最新研究成果，并指出了继续研究的机会。
The reduction of gaseous nitrogen (N2) is a challenge for industrial, biological and synthetic chemists, who want to understand the formation of ammonia (NH3) for agriculture and also want to form N-C and N-Si bonds for fine chemical synthesis. The iron-molybdenum active site of nitrogenase has inspired chemists to explore the ability of iron and molybdenum complexes to bring about transformations related to N2 reduction. This area of research has gained significant momentum, and the last two years have witnessed a number of significant advances in synthetic Fe-N2 and Mo-N2 chemistry. In addition, the identities of all atoms in the iron-molybdenum cofactor of nitrogenase have finally been elucidated, and the discovery of a carbide has generated new questions and targets for coordination chemists. This Perspective summarizes the recent work on iron and molydenum complexes, and highlights the opportunities for continued research.
