Abstract
The increased Lewis acidity in organotin-functionalized crown ethers XSnCH[19]-crown-6 (5, X = I; 6, X = Br; 7, X = Cl) not only resulted in ditopic complexation of sodium/potassium halides, but also offers an excellent strategy to manipulate through intramolecular O→Sn interactions the selectivity of the crown ether moiety towards Na/K depending on the solvent.
摘要
有机锡官能化冠醚XSnCH[19]-冠-6（5，X = I；6，X = Br；7，X = Cl）中路易斯酸性的增强不仅导致了卤化钠/钾的双位点络合，还提供了一种通过分子内O→Sn相互作用根据溶剂来操控冠醚部分对Na/K选择性的出色策略。
