摘要
本文总结了饱和漆酚双冠醚电子电离质谱的裂解规律。十个测试样品的结构均为二个芳香冠醚通过NHCORCONH对称桥连而成。当R为烷基时,裂解首先发生在酰胺键或其邻近的键上。R为芳基时则在分子的冠醚部份首先发生裂解。文中还叙述了在某些化合物中的特殊的氢重排反应。
The fragmentation reactions of the saturated urushiol biscrown ether in EIMS are Summu-rized in this paper. The structure of all ten tested compounds are symmetical biscrown ether(aromatic) bridged by NHCORCONH group. The cleavage first occurs at C--N bond of amideor its vicinal bond when R is an alkyl. But R is an aromatic group the cleavage at the crownether parts in their molecules is predominant process. The specific hydrogen rearangememt reac-tions in some compounds are also described in the text.
