In this study, 28-membered macrocyclic 1,5(1,5)-di(1,5-diaza-3,7-diphosphacyclooctana)-2,4,6,8(1,4)-tetrabenzenacyclooctaphane were synthesized by condensation of pyridinephosphine, paraformaldehyde, and primary diamines (bis(4-aminophenyl)methane or -sulfide. The first representatives of binuclear copper(I) complexes of P,N-containing cyclophanes with two 1,5-diaza-3,7-diphosphacyclooctane rings incorporated into a macrocyclic core and intracavity location of unusual, developed angle CuI moiety were obtained. The structure of one complex was established by X-ray diffraction analysis. The complexation led to a slight distortion of the cyclophane conformations.
在这项研究中，通过缩合吡啶膦、多聚甲醛和仲二胺（双（4-氨基苯基）甲烷或 - 硫醚）合成了 28 元大环 1,5(1,5)-二（1,5-二氮杂-3,7-二膦环辛烷）-2,4,6,8(1,4)-四苯并环辛烷。首次获得了具有两个 1,5-二氮杂-3,7-二膦环辛烷环的含 P,N 的双铜 (I) 配合物的双核铜 (I) 配合物的代表，这些配合物被纳入大环核内和腔内，具有不寻常的、发达角度的 CuI 部分。通过 X 射线衍射分析确定了一个配合物的结构。配合物导致了环芳烃构象的轻微扭曲。
