Organopalladium Complexes of Oxacalixarenes: Selecting the Lid for the Three-Dimensional Scaffold

The first organometallic (palladium) complexes of oxacalixarene molecules were prepared via oxidative addition of the C–I bond at the lower rim. The unique geometry of the oxacalixarene scaffold allowed for the selective introduction of new ligands at the top of the calixarene scaffold. Such coordination can be used to coordinatively link the opposing aromatic rings.

首例氧杂杯芳烃（oxacalixarene）类有机金属钯（palladium）配合物通过下缘碳碘键的氧化加成反应制备得到。氧杂杯芳烃骨架独特的几何构型允许在杯芳烃骨架上端选择性引入新型配体。此类配位作用可用于实现相对芳香环之间的配位连接。
