采用低温停流技术研究了二氧与三齿配体1,1,4,7,7-五甲基二乙基三胺（Me(5)dien）的铜(I)配合物的反应。在低温下，双（mu-oxo）铜（III）配合物作为反应中间体的形成可以被光谱检测到，并对该体系进行了定量动力学分析。铜(II)配合物的晶体结构((Me-bpa)铜(Cl) (2)] (1), ({(Me-bpa)铜(Cl) (ClO4)} (2)] (2), ({(MeL)铜(Cl) (ClO4)}(2)(3),和((MeL)铜(nc) (2) (4) (Me-bpa = N-methyl - (bis (2-pyridyl)甲基)胺;MeL= n -甲基[（2-吡啶基）乙基（2-吡啶基）甲基]胺)。(c) 2007 Elsevier B.V.版权所有
The reaction of dioxygen with the copper(I) complex of the tridentate ligand 1,1,4,7,7-pentamethyldiethylenetriamine (Me(5)dien) has been investigated using low-temperature stopped-flow techniques. The formation of a bis( mu-oxo)copper(III) complex as a reactive intermediate could be detected spectroscopically at low temperatures and a quantitative kinetic analysis was performed for this system. Crystal structures of the copper(II) complexes [(Me-bpa)Cu(Cl)(2)] (1), [{(Me-bpa)Cu(Cl)(ClO4)}(2)] (2), [{(MeL)Cu(Cl)(ClO4)}(2)] (3), and [(MeL)Cu(NCS)(2)] (4) (Me-bpa=N-methyl-[bis(2-pyridyl)methyl]amine; MeL=N-methyl-[(2-pyridyl)ethyl(2-pyridyl)methyl]amine) are reported.
