A copper complex, [Cu(tmpa)(MeCN)], effectively reductively couples NO 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 Cu + NO, leading to Cu-mediated NO-disproportionation. The relationship of this chemistry to biological iron and/or copper mediated NO reductive coupling to give NO is discussed.
一个铜配合物，[Cu(tmpa)(MeCN)]，在甲醇（MeOH）中有效地将 NO 在 RT 下还原偶联，得到结构表征的低亚硝酰二铜（II）加合物。甲醇的氢键对于低亚硝酰配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相反的氧化还原过程，生成 Cu + NO，导致 Cu 介导的 NO 歧化。讨论了这种化学与生物铁和/或铜介导的 NO 还原偶联生成 NO 的关系。
