The ligand TMPA (tris(2-pyridylmethyl)amine) and its copper complexes have played a prominent role in recent (bio)inorganic chemistry studies; the copper(I) complex [CuI(TMPA)(CH3CN)]+ possesses an extensive dioxygen reactivity, and it is also known to effect the reductive dechlorination of substrates such as dichloromethane and benzyl and allyl chlorides. In this report, we describe a set of new analogues
配体TMPA(三(2-吡啶基甲基)胺)及其铜络合物在最近的(生物)无机化学研究中发挥了重要作用。铜(I)配合物[CuI(TMPA)(CH3CN)] +具有广泛的双氧反应性,并且还已知会实现底物(例如二氯甲烷,苄基氯和烯丙基氯)的还原脱氯。在本报告中,我们描述了一组新的TMPA类似物,配体6TMPAOH,双核Iso-DO和三核SYMM类似物。具有这些配体和先前描述的双核配体DO的铜(I)配合物与氯仿反应,导致还原性脱氯并生成[CuIIx(L)Clx] x +(x = 1、2或3)。[CuII(6TMPAOH)Cl] PF6,[CuII2(Iso-DO)Cl2](PF6)2,[CuII2(DO)Cl2](PF6)2和[Cu3(SYMM)Cl3]( PF6)3,化合物的特征还在于紫外可见光谱和EPR光谱以及循环伏安法。比较了吡啶基6取代基(与6TMPAOH,Iso-DO和SYMM形成的配合物)对
