| Abstract | Growing awareness of the environmental impact caused by the chemical industry drives considerations towards a circular economy and the use of renewable electricity. A key role will be played by ammonia (NH3) currently produced in the Haber Bosch process at elevated temperature and pressure from fossil hydrogen leaving an enormous CO2 footprint. A more sustainable production is to be realized by electrochemically generated hydrogen or all-electrochemical synthesis. Aside from the crucial role in fertilizer production, NH3 is necessary for the synthesis of organic intermediates and monomers via C-N bond formation reactions. This perspective highlights different strategies for electrochemical C-N functionalisation focusing on electrophilic nitration. Based on literature from one century, syntheses involving different inorganic nitrogen sources are discussed and their potential is evaluated. Finally, a perspective for more sustainable electrochemical nitration using NH3 and atmospheric nitrogen (N2) is presented. This way, a possibility to bypass the Haber Bosch process shall be demonstrated especially for decentralized small-scale productions. Rethinking nitration: sustainable electrochemical C-N functionalization. This work reviews diverse inorganic nitrogen sources for fine chemical production, with a perspective on innovative pathways to harness alternative nitrogen sources' potential. |
