摘要

我们研究了手性咪唑啉基 C2 对称配体与锌（II）和铜（II）的配位化学。我们研究了两种类型的双咪唑啉配体，一种是游离胺（BIM-H），另一种是在第 6 位被甲苯磺酰基保护的胺（BIM-Ts）。所形成的配合物经过分离、纯化和表征，特别是通过 X 射线衍射研究和对映体纯度配合物的 CD 分析。通过对配体体系（对映纯或外消旋体）的选择，我们能够证明，通过双咪唑啉配体的手性分子指令，可以控制同色和异色金属配合物的选择性形成。

Chiral Self-Sorting Process With C2 Symmetric Bisimidazoline Ligands

We have studied the coordination chemistry of chiral imidazoline-based C₂-symmetric ligands with zinc (II) and copper (II). Two types of bisimidazoline ligands were studied, one with the free amine (BIM-H) and the other with the amine protected by a toluene sulfonyl group in position 6 (BIM-Ts). The complexes formed were isolated, purified, and characterized, in particular by X-ray diffraction studies and CD in the case of the enantiopure complexes. By playing with the choice of ligand system (enantiopure or racemate), we were able to show that the selective formation of homoleptic and heteroleptic metal complexes can be controlled by means of the chiral molecular instruction of bisimidazoline ligands.

期刊介绍： The main aim of the journal is to publish original contributions of scientific work on the role of chirality in chemistry and biochemistry in respect to biological, chemical, materials, pharmacological, spectroscopic and physical properties. Papers on the chemistry (physiochemical, preparative synthetic, and analytical), physics, pharmacology, clinical pharmacology, toxicology, and other biological aspects of chiral molecules will be published.
