取代10H—吡啶并[1,2—a]吲哚盐的^1HNMR与结构的关系

The Relationship Between ~1H NMR and Structure of Substituted 10H-Pyrido[1,2-a] indolium Perchlorates

本文对取代10H-吡啶并[1,2-a]吲哚盐的核磁共振氢谱进行了研究,通过讨论6,8位取代基对吡啶环氢化学位移的影响发现8位取代基显著地改变了δ值,而6位取代基则对δ影响较小。

The 1H NMR of a series of substutited 10H-pyrido [1,2-a]-indolium perchlorates have been studied. The effect of substituents on chemical shift of pyridine hydrogens was discussed. It was found that δ values were changed much more greatly by 8-substituted groups than by 6-substituted ones.
