supporting ligand influences the relative stability of isomeric mu-eta 2:eta 2-peroxo- and bis(mu-oxo)dicopper complexes, a comparative study was undertaken of the O2 reactivity of Cu(I) compounds supported by the 10- and 12-membered macrocycles, 1,4,7-R3-1,4,7-triazacyclodecane (R3TACD; R = Me, Bn, iPr) and 1,5,9-triisopropyl-1,5,9-triazacyclododecane (iPr3TACDD). While the 3-coordinate complex [(iPr3TACDD)Cu]SbF6
为了了解三齿大环支撑配体的性质如何影响异构的mu-eta 2:eta 2-过氧-和双(mu-oxo)二铜配合物的相对稳定性,进行了对O2反应性的比较研究。由10和12元大环,1,4,7-R3-1、4,7-三氮杂环癸烷(R3TACD; R = Me,Bn,iPr)和1,5,9-三异丙基支撑的Cu(I)化合物-1,5,9-三氮杂环十二烷(iPr3TACDD)。尽管三坐标配合物[(iPr3TACDD)Cu] SbF6与O2不反应,但[-(R3TACD)Cu(CH3CN)] X(R = Me或Bn; X = ClO4-或SbF6-)在-80摄氏度下氧化紫外-可见光谱和共振拉曼光谱表明,生成了双(mu-oxo)物质[(R3TACD)2Cu2(mu O)2] X2。有趣的是,与先前报道的1,4,7-三异丙基-1,4,7-三氮杂环壬烷(iPr3TACN)支持的系统不同,产生过氧化合物和双(mu-oxo)化合物的互变混合物(Cahoy,J
