The syntheses of novel cage-functionalized crown ethers,11–13, that contain one or more pyridyl units are reported. The results of alkali metal picrate extraction experiments performed by using11 and12 are compared with those obtained by using the corresponding model (non-cage) crown ethers. Cage-functionalized crown ether11 displays greater avidity toward Li+ picratevis-a`-vis the corresponding model
据报道,含有一个或多个吡啶基单元的新型笼功能化冠醚11-13的合成。将使用11和12进行的碱金属苦味酸盐提取实验的结果与使用相应的模型(非笼式)冠醚获得的结果进行比较。笼功能化的冠醚11相对于相应的模型系统2对Li +苦味酸显示出更高的亲和力,而12相对于其相应的模型系统3则对从水溶液中提取碱金属苦味酸显示出更高的亲和力。氯仿3。此外,还准备了一个高度组织化的笼状环穴体,16。发现这种不寻常的宿主分子对提取Li +和Na +苦味酸盐具有很高的选择性。图选项
