A coppercomplex, [CuI(tmpa)(MeCN)]+, effectively reductively couples NO(g) at RT in methanol (MeOH), giving a structurally characterized hyponitrito-dicopper(II) adduct. Hydrogen-bonding from MeOH is critical for the hyponitrite complex formation and stabilization. This complex exhibits the reverse redox process in aprotic solvents, giving CuI + NO(g), leading to CuI-mediated NO(g)-disproportionation
铜配合物 [CuI(tmpa)(MeCN)]+ 可在室温下在甲醇 (MeOH) 中有效还原偶合 NO(g),得到结构特征明确的次亚硝基二铜 (II) 加合物。甲醇中的氢键对于次亚硝酸盐络合物的形成和稳定至关重要。该配合物在非质子溶剂中表现出反向氧化还原过程,产生 CuI + NO(g),导致 CuI 介导的 NO(g) 歧化。讨论了该化学与生物铁和/或铜介导的 NO(g) 还原偶联生成 N2O(g) 的关系。
