已经公开了2,2'-二叠氮联苯对C 60和Sc 3 N@ I h -C 80的不同反应性。就 C 60而言,脱芳香级联反应导致形成与 7-6-5 元环系统融合的氮杂富勒烯,而 Sc 3 N@ I h -C 80则经历 CH 插入途径,其中生成咔唑衍生的[6,6]-和[5,6]-氮杂金属富勒烯以及不寻常的1,2,3,6-四氢吡咯并[3,2- c ]咔唑衍生的金属富勒烯。

A generalmethod for a highly regioselective copper-catalyzed cross-coupling of two aromatic compounds using iodine as an oxidant has been developed. The reactions involve an initial iodination of one arene followed by arylation of the most acidicC-H bond of the other coupling component. Cross-coupling of electron-rich arenes, electron-poor arenes, and five- and six-membered heterocycles is possible
