A novel nitrogen‐doped corannulene derivative, 8‐tert‐butyl‐6b2‐azapentabenzo[bc,ef,hi,kl,no]corannulene, was synthesized by 1,3‐dipolar cycloaddition of a polycyclic aromatic azomethine ylide with a diarylethyne and subsequent palladium‐catalyzed intramolecular cyclization. This molecule represents the first example of a corannulene derivative bearing an internal heteroatom, and exhibits unique structural
通过多环芳族偶氮甲亚胺叶立基与二芳基乙炔的1,3-偶极环加成反应,合成了一种新型的氮掺杂的香兰环烯衍生物8-叔丁基-6b 2-氮杂五苯并[bc,ef,hi,kl,no]环戊二烯。随后钯催化的分子内环化。该分子代表带有内部杂原子的香兰环烯衍生物的第一个例子,与母体香兰环烯相比,由于引入氮原子和扩展的π共轭而表现出独特的结构和物理性质。
