摘要

直到最近，试图再生sm2以产生催化循环的尝试一直受到与所使用的质子源（如水和醇）的共轭碱形成稳定的氧加合物的阻碍。这些研究人员先前开发了一种系统，使用非配位2,6-二甲基吡啶作为质子供体，允许电催化钐还原剂循环。现在将其与Mo钳形配合物（[Mo]）结合，作为N2到NH3转化的电催化剂，他们能够在施加的电位下实现催化转换（在化学计量条件下，相对于Sm的8.4等价物，0.3等价物）。据报道，82%的法拉第（电荷对产物）效率与现有的非水锂介质体系相比要好，并且在- 1.45 V的负电势下实现（与二茂铁/二茂铁偶联相比）。虽然效率和过电位相当有希望，但在考虑这些方法的实际实施时，有限的营业额仍然是一个重大问题。尽管如此，将sm介导方案添加到非水N2R工具箱中代表了该方向的重大推动。
