Synthesis and Structural Analysis of a Highly Curved Buckybowl Containing Corannulene and Sumanene Fragments

Buckybowls 7, 9, and 10 were prepared from benzo[k]fluoranthene 6 and fluoranthene 8 using straightforward procedures involving key palladium-catalyzed cyclization reactions. The structures of bowl-shaped molecules 7 and 10 were determined by using X-ray crystallographic methods. The observed p-orbital axis vector (POAV) angle of 7 was found to be 12.8°.本研究以苯并[k]荧蒽（benzo[k]fluoranthene）6与荧蒽（fluoranthene）8为原料，通过包含关键钯催化环化反应的简便合成流程，制备得到巴基碗（Buckybowls）7、9与10。碗状分子7与10的结构经X射线晶体衍射方法得以确证。经测定，分子7的p轨道轴向量（p-orbital axis vector，POAV）角为12.8°。
