one six-membered ring, whose bond lengths are equalized, and another ring, whose bond lengths are alternated, has been prepared via one-electron oxidation of a benzene annelated with three bicyclo[2.1.1]hexene units. The structure has been determined by X-ray crystallography and the aromaticity of two benzene rings estimated by theoretical calculations. Although the former six-membered ring has a higher
通过对与三个双环[2.1.1] 己烯单元退火的苯进行单电子氧化,制备了一种全新的萘,具有一个键长相等的六元环和另一个键长交替的环。该结构已通过 X 射线晶体学确定,两个苯环的芳香性由理论计算估计。尽管前六元环具有更高的芳香度,但由于其中包含更大的应变,已发现它对单线态氧更具反应性。这些结果已通过理论计算得到解释。
