A couple of enantiomers of novel chiral macrocyclic imines based on R/S-camphor were asymmetrically synthesized. Through the chiral macrocyclic ligands, enantiomers of nickel(II) coordination compounds were obtained. The chirality of the ligand was transferred to the nickel atom upon coordination, leading to predetermined configuration. The chiral ligands and corresponding nickel coordination compounds were characterized by UV, IR, CD, VCD spectra and single crystal X-ray crystallography. The structural and spectroscopic properties were further investigated by DFT calculations.
一对新型手性大环亚胺的对映异构体基于 R/S-莰烯不对称合成。通过手性大环配体，得到了镍（II）配位化合物的对映异构体。配体的手性在配位时转移到镍原子上，从而得到预定的构型。手性配体和相应的镍配位化合物通过 UV、IR、CD、VCD 光谱和单晶 X 射线晶体学进行了表征。通过 DFT 计算进一步研究了结构和光谱性质。
