Two new BINOL-based chiral crown ether/ammonium complexes are studied by travelling-wave ion-mobility spectrometry. Homo- and heterochiral crown ether/ammonium complexes differ in their collision cross sections, and these differences go along with changes in hydrogen bonding as revealed by gas phase H/D-exchange experiments. Applications for the determination of enantiomeric excess are discussed.
两个新的基于 BINOL 的手性冠醚/铵络合物通过行波离子迁移谱进行了研究。同手性和异手性冠醚/铵络合物在其碰撞截面方面存在差异，这些差异与气相 H/D 交换实验所揭示的氢键变化有关。讨论了用于确定对映体过量的应用。
