| 摘 要： | 为了探讨含手性蒎烯基联吡啶的手性钼(0)络合物的结构对光谱(特别是CD光谱)性质的影响,合成了两个新型手性钼络合物( )CD452Mo(CO)4(LRR)]和Mo(CO)4(LSS)].用元素分析、IR、UV vis、CD、1HNMR和13CNMR等对其进行了充分表征.研究结果表明:两种络合物为一对具有几乎完全相同物理化学性质、配体互为对映体的光学异构体;两者在可见区的CD曲线呈现弱Cotton效应,且大致为镜象对称,说明在相应的手性络合物中,由于联吡啶上相反手性的蒎烯基通过中心金属钼对MLCT发色团产生了手性微扰作用,从而产生诱导CD效应.

| Abstract: | A pair of novel chiral complexes ( )~(CD)_(452)Mo(CO)_4(L~(RR))] and (-)~(CD)_(452)Mo(CO)_4(L~(SS))] were prepared and characterized by EA, UV-vis, IR, NMR and CD spectra in order to investigate the influence of structures on the spectral (especially CD) properties of chiral molybgenum(0) complexes with chiral pineno-bipyridines. The results reveal that the two chiral complexes have almost the same physico-chemical properties and they are a pair of optical isomers with the enantiomeric ligands. Their CD spectra in the visible range show weak Cotton effects, which are approximately of mirror image, indicating that the appended pineno-groups with opposite chirality in bipyridines can perturb the MLCT chromophores in the related complexes through the molybgenum centers respectively and lead to induced CD effects. |
