考虑到它们极负的氧化还原电位(例如,Li+→Li(0),−3.04 V;K+→K(0),−2.93 V), 1族金属阳离子的化学还原是无机化学中最大的挑战之一:它们在合成化学体系中被广泛认为是不可还原的。它们的还原通常需要苛刻的电化学条件。在此,我们提出了一种新的策略:通过杂双金属电子中间体和使用非结合的“自由”电子作为还原剂。基于我们之前报道的K+[LiN(SiMe3)2]e -杂双金属电极,我们证明了K+和Li+阳离子的可还原性。此外,我们发现外部路易斯碱配体,即三[2-(二甲氨基)乙基]胺(Me6Tren)或2,2,2-密码体,可以通过更好地结合Li+ (Me6Tren)或K+(2,2,2-密码体)来发挥一定程度的还原选择性,从而将电子推到另一个阳离子上。
Given their very negative redox potential (e.g., Li+ → Li(0), −3.04 V; K+ → K(0), −2.93 V), chemical reduction of Group-1 metal cations is one of the biggest challenges in inorganic chemistry: they are widely accepted as irreducible in the synthetic chemistry regime. Their reduction usually requires harsh electrochemical conditions. Herein we suggest a new strategy: via a heterobimetallic electride intermediate and using the nonbinding “free” electron as reductant. Based on our previously reported K+[LiN(SiMe3)2]e– heterobimetallic electride, we demonstrate the reducibility of both K+ and Li+ cations. Moreover, we find that external Lewis base ligands, namely tris[2-(dimethylamino)ethyl]amine (Me6Tren) or 2,2,2-cryptand, can exert a level of reducing selectivity by preferably binding to Li+ (Me6Tren) or K+ (2,2,2-cryptand), hence pushing the electron to the other cation.
