| 中文摘要: |
| 以羧酸铑(II)为母体，吡啶-2-基(吡啶-4-基)甲酮(24ma)为轴向配体，合成了4种新型羧酸铑(Ⅱ)轴向配合物，且成功培养出化合物单晶。使用1H NMR、13C NMR、MS、IR和X-单晶射线衍射对其结构进行表征，讨论了取代基和轴向配体对分子结构的影响，并初步测试了它们对美罗培南类化合物合成反应的催化性能。结果表明，与母体分子羧酸铑(II)相比，所选定的羧酸铑(Ⅱ)轴向配合物因在反应体系中溶解度较差、配体不易解离等原因，导致催化合成美罗培南类化合物的产率不高。 |
| 英文摘要: |
| Four novel axial complexes of rhodium(Ⅱ) carboxylate pyridin-2-yl(pyridin-4-yl) ketone were synthesized with rhodium(II) carboxylate as the main body, and the single crystals were successfully grown. Their structures were characterized by 1H NMR, 13C NMR, MS, IR and X-ray single crystal diffractions. The effects of substituents and axial ligands on the molecular structure were discussed, and their catalytic properties for the synthesis of meropenem like compounds were preliminarily tested. The results showed that compared with the parent molecule rhodium carboxylate(II), the selected axial complex of rhodium carboxylate(II) had poor solubility in the reaction system, and the ligand was not easy to dissociate, which led to the low yield of catalytic synthesis of meropenem compounds. |
