合成了中心空腔含有甲基的两个环番，并测定了它们的X-射线结构。其中一个分子在氢原子和甲基之间有一个非常短的非键合接触，另一个是含有两个向内的甲基的大双环化合物的第一个例子。
Twoin,in-cyclophanes that contain methyl groups in their central cavities have been synthesized, and their X-ray structures have been determined. One of these molecules contains a very short nonbonded contact between a hydrogen atom and a methyl group, and the other is the first example of a macrobicyclic compound that contains two inwardly directed methyl groups.
