内嵌金属富勒烯（Endohedral Metallofullerenes，EMF），即在富勒烯中空的内部含有金属原子或金属团簇的富勒烯，具有多种迷人的性质，在生物医学、电子学和材料科学等领域有着广阔的应用前景。[1-4]自从第一次报道了EMF的外笼加合物的合成以来，EMF的化学修饰引起了人们的极大关注，因为EMF的化学修饰可以通过将不同的官能团连接到外部笼上来调节EMF的性质，从而提供比母体EMF更有合成用途的衍生物。虽然EMF的化学研究不如空富勒烯的化学研究广泛报道，近年来已经合成了各种EMF衍生物并对其进行了充分的表征。[1-19]在取代基和富勒烯笼之间含有封闭的五元或六元环的EMF的环加合物衍生物已经使用例如1，3-偶极加成或Diels-Alder反应合成。[6-8]相比之下，形成三元环通常导致富勒烯笼的开放，从而提供开放结构衍生物。代表性实例是Y3N@C80 [9]的宾格尔加合物和金刚烷亚基EMF衍生物。[10-15]
Endohedral metallofullerenes (EMFs), that is, fullerenes with metal atoms or metallic clusters trapped inside their hollow interiors, have a variety of fascinating properties and promising applications in many fields, such as biomedicine, electronics, and materials science.[1–4] Since the first reported synthesis of exohedral adducts of EMFs,[5] chemical modification of EMFs has attracted significant attention because of the potential to tune the properties of the EMF by attaching different functional groups onto the external cage, thereby affording derivatives that are more synthetically useful than the parent EMFs.Although the chemical investigation of EMFs has been less widely reported than that of empty fullerenes, various EMF derivatives have been synthesized and thoroughly characterized during recent years.[1–19] Cycloadduct derivatives of EMFs that contain closed five-or six-membered rings between the substituent and the fullerene cage have been synthesized using, for example, 1, 3-dipolar additions or Diels–Alder reactions.[6–8] In contrast, the formation of threemembered rings typically results in an opening of the fullerene cage, thus affording open structure derivatives. Representative examples are the Bingel adducts of Y3N@ C80 [9] and the adamantylidene EMF derivatives.[10–15]
