Despite their unique structures, tantalizing properties, and potential applications in carbon nanoscience and technology, the synthesis and functionalization of zigzag hydrocarbon nanobelts have remained largely unexplored until recently. Reported herein is the selective transformations of belt[4]arene[4]tropilidenes and their application in the construction of novel belts. The oxidation of belt[4]arene[4]tropilidene with benzeneseleninic anhydride under controlled conditions selectively afforded mono- to tetrakis(α-diketone)-functionalized belt intermediates. A subsequent condensation reaction with 1,2-phenylenediacetonitrile and 1,2-phenylenediamine produced a diversity of unprecedented belts with various macrocyclic cavities.

带[4]芳烃[4]托吡烯的选择性氧化及其在构造扩腔截锥结构烃带中的应用

尽管它们具有独特的结构、诱人的特性以及在碳纳米科学和技术中的潜在应用，但锯齿形碳氢纳米带的合成和功能化直到最近仍然在很大程度上未被探索。本文报道了带[4]芳烃[4]聚二烯的选择性转化及其在新型带建设中的应用。在受控条件下用苯硒酸酐氧化带 [4] 芳烃 [4] tropilidene 选择性地提供单到四（α-二酮）功能化的带中间体。随后与 1,2-苯二乙腈和 1,2-苯二胺的缩合反应产生了具有各种大环空腔的各种前所未有的带。
