Abstract

Hexagon-shaped [6 + 6] Schiff-base macrocycles with 12 imine bonds are reported. These giant macrocycles possess 6 N2O2 coordination environments and mass spectrometry evidence for hexametallation of one macrocycle is provided. Semi-empirical calculations reveal two stable conformations with boat and chair geometries for the macrocycles metallated with Ni(II), analogous to the conformations observed for cyclohexane.

摘要

报道了具有12个亚胺键的六边形[6 + 6]席夫碱大环化合物。这些巨型大环化合物具有6个N2O2配位环境，并提供了一个大环六金属化的质谱证据。半经验计算揭示了用Ni(II)金属化的大环化合物具有船式和椅式几何形状的两种稳定构象，类似于环己烷所观察到的构象。
