We have established the Rh-catalyzed high-yielding and highly 1,3,5-selective [2+2+2] cycloaddition of push-pull internal alkynes. This reaction allows for the shape- and size-tunable synthesis of covalent organic cages (aryl ether cages) using push-pull internal diynes. Some aryl ether cages encapsulated isolated water molecules in their hydrophobic cavity by hydrogen bonding with the multiple ester
我们已经建立了 Rh 催化的高产率和高 1,3,5 选择性 [2+2+2] 推拉内炔烃环加成反应。该反应允许使用推拉内部二炔来合成形状和尺寸可调的共价有机笼(芳基醚笼)。一些芳基醚笼通过与多个酯部分形成氢键将孤立的水分子封装在它们的疏水空腔中。
