| 摘 要： | 本文测定了九个苯并冠醚的13C-NMR和1H-NMR谱,结合元素分析、红外、紫外、质谱等数据,确定了这些冠酸的分子结构。根据NMR谱的谱线位置、裂分情况及取代基诱导效应,归属了全部13C-NMR谱线。并讨论了苯环上不同取代基对冠醚环上各碳化学位移的影响。

| Abstract: | The 13C-NMR and 1H-NMR spectra of nine benzo-15-crown-5 are recorded. Comibned with microanalyses, infrared, ultraviolet and mass spectroscopy data, the molecular structures of the crowns are determined. All the 13C-NMR spectral lines are assigned based on the line positions and splittings as well as substituent inductive effects. The influences of benzine ring's different sub-stituets on the chemical shifts of crown's carbons are also discussed. |
