Hydrides mediate nitrogen fixation
WebHydrides mediate nitrogen fixation Qianru Wang, 1 ,24Yeqin Guan, Jianping Guo, and Ping Chen 3 * SUMMARY The fixation of atmospheric dinitrogen to ammonia is crucial for the sustainable growth of human society. The reduction of N 2 to NH 3 needs the inputs of electrons and hydrogens, which could be sup-plied by hydridic hydrogens. http://www.syb.cas.cn/ydhz/kjdt/202403/t20240301_6379370.html

Web21 mrt. 2024 · Nitrogen is first fixed through the reduction of N2 by alkali or alkaline earth metal hydrides to form imides and, subsequently, the imides are hydrogenated to … Web12 mei 2016 · Hydrides have been incorporated into synthetic systems, which can bind N 2, reduce some nitrogenase substrates, and/or reductively eliminate H 2 to generate reduced iron centers. Though some carbide-containing iron clusters are known, none yet have sulfide bridges or high-spin iron atoms like the FeMoco. Cited By
Web5 sep. 2024 · Alkali or alkaline earth metal hydrides can fix N2, forming corresponding metal imides and H2. The metal imides then undergo hydrogenation to NH3 and metal hydrides. However, the reaction mechanisms of N2 activation, H2 release and NH3 formation over alkali hydrides are still unclear. Web3 mei 2024 · Stochiometric reactions with hydride containing precatalysts reveal a hydrogen evolution cycle in which no nitrogen fixation occurs. Irradiation of the dihydride precatalysts, observed during turnover, results in H 2 elimination and formation of (P 2 P Ph )Fe (N 2) 2, which itself is unreactive with acids at low temperature.
http://imide.dicp.ac.cn/English_/Home/Bright_work.htm WebWe have found that some vanadium complexes worked as effective catalysts toward reduction of molecular dinitrogen into silylamine under ambient reaction conditions, where up to 24 equiv of N(SiMe3)3 are produced based on the vanadium atom. This is the first successful example of the vanadium-catalyzed transformation of nitrogen gas into …
