环丙烷衍生物在CD3OD离子体系中的H/D交换反应

摘要

The fragmentation properties of the product ions [M＋1]＋，[M＋2]＋and [M＋3]＋ formed by ion-molecule reaction of four cyclopropane derivatives with the ion system of CD3OD were investigated by using collision-induced dissocation technique. The experiment results indicated that the product ions were produced via the H/D exchange reaction between reactants and reactive reagent ions of CD3OD. There are two exchangable hydrogen atoms on the ring of compounds 1 and 2, and only one for compound 3 and 4.%研究了环丙烷衍生物在CD3OD离子体系中的H/D交换反应产物离子[M＋1]＋、[M＋2]＋和[M＋3]＋的碰撞诱导碎裂(CID)反应特征。实验结果表明这些产物离子是由反应物与试剂离子之间发生H/D交换反应生成的。获得了环丙烷衍生物结构中活泼氢位置及其数量的信息。
