with p-anisyl substituents by analogous long-chain ligands bearing appropriate end-functions (azide), the double threading process is as efficient as with the shorter (p-anisyl) chelates. An efficient quadruple end-functionalization reaction based on the copper(I)-catalyzed Huisgen 1,3-dipolarcycloaddition (“click” chemistry) affords the desired iron(II)-complexed two-string [3]rotaxane in excellent
八面体铁(II)中心的三维模板效应已被用于穿过两个配位分子单元,每个单元都是带有对茴香基的双齿 3,3'-二异喹啉配体,通过一个配位的 41 元大环含有相同的内环但非空间位阻螯合物。双螺纹过程是由三个双齿配体与铁 (II) 中心的配位驱动的。通过用带有适当末端官能团(叠氮化物)的类似长链配体替换用对茴香基取代基修饰的线,双穿线过程与较短的(对茴香基)螯合物一样有效。基于铜(I)催化的Huisgen 1的高效四重末端官能化反应,

incorporating a 3,3′-biisoquinoline (biiq) chelate. The biiq ligand bears phenyl groups at its 8- and 8′-positions, which provide it with an approximate crescent shape. The incorporation of the 8,8′-diaryl-3,3′-biisoquinoline motif in a ring leads to an unusual situation. The complexing site of the macroring is unambiguously pointing towards the inner part of the macrocycle, but, at the same time, it is not
