H-苯并[ cd ] py('Olympicene')是一种多芳烃和石墨烯的非Kekulé片段。已开发出一种新的合成方法来形成6 H-苯并[ cd ] py和相关的酮,包括首次分离不稳定的醇6 H-苯并[ cd ] pyren-6-ol。用扫描隧道显微镜(STM)和非接触原子力显微镜(NC-AFM)对反应产物进行分子成像,表征了6 H-苯并[ cd ] re以及以前无形且稳定性较差的5 H-苯并[ cd ] py,完全共轭的苯并[ cd]戊基自由基与酮类为氧化产物。

on the aromaticcore and a tethered alkyl moiety provides a straightforward approach to access these scaffolds; however, such a strategy is often hampered by the need of special reactive groups and/or less compatible cyclization conditions. It would be synthetically appealing if a common native functional group can be used as a handle to enable a general C–H annulation with diverse aromatic rings.
