The synthesis of an iodine-doped sumanene, which represents the first example of halogen-doped buckybowls, is described. Pristine trithiasumanene, trisilasumanene and the hitherto unknown parent triselenasumanene, three interesting heterobuckybowls with significant synthetic challenges, were efficiently prepared from the iodine-doped sumanene through non-pyrolytic conditions. This work demonstrates the high potential of hypervalent iodines embedded in extended π-conjugated systems for the synthesis of novel curved and planar polycyclic aromatic hydrocarbons.
本文描述了碘掺杂苏曼烯的合成，这是卤素掺杂巴基碗的首个实例。通过非热解条件，由碘掺杂苏曼烯高效制备出了原始的三硫代苏曼烯、三硅代苏曼烯以及迄今未知的母体三硒代苏曼烯，这三种有趣的杂巴基碗合成颇具挑战。这项工作展示了嵌入扩展π共轭体系的高价碘在合成新型弯曲和平面多环芳烃方面的巨大潜力。
