can be filled with gases (H2, He, Ne) in the solid state, and the cage opening then contracted in situ by raising the temperature to complete an intramolecular Wittig reaction, trapping the atom or molecule inside. Known transformations complete conversion of the product fullerene to C60 containing the endohedral species. As well as providing an improved synthesis of large quantities of 4He@C60, H2@C60
在孔口边缘包含
磷叶立德和羰基部分的开笼
富勒烯可以在固态下充满气体(H 2 、He、Ne),然后通过升高温度原位收缩笼开口以完成分子内维蒂希反应,将原子或分子捕获在内部。已知的转化完成了产物
富勒烯向含有内嵌体物质的C 60的转化。该方法不仅改进了大量4 He@C 60 、H 2 @C 60和 D 2 @C 60的合成,还允许有效掺入昂贵的气体(例如 HD 和3 He),以制备 HD@ C 60和3 He@C 60 。该方法还首次通过分子手术合成了 Ne@C 60 ,并通过晶体学和13 C NMR 光谱对其进行了表征。
