茚满酮型双苯并冠醚的结构表征

STRUCTURE CHARACTERIZATION OF INDONE DIBENZO-24-CROWN-8

测试了三种茚满酮型双苯并冠醚的红外光谱、紫外光谱、质谱、氢核磁共振谱、碳核磁共振谱和元素分析等数据,对这些数据进行了解析,从而确定了这三种新化合物的结构.根据碳核磁共振谱线的位置和裂分情况,归属^(13)C-NMR 谱线.

The IR,UV,MS,~1H-NMR,^(13) C-NMR and elemental analysis data are recorded.The data are analysed.And the molecul arstruetures of the crown ethers are determined.The ^(13) C-NMR spectral lines are assigned by the line position and splittings.
