1,8-naphthylene–ethynylene compounds underwent thermal isomerization into acenaphtho[1,2-a]pyrene derivatives, and the structure of the new polycyclic aromatic system was established by X-ray analysis. The mechanism of the isomerization is explained in terms of sequential cyclization reactions via biradical intermediates followed by hydrogen migration.
将标题的1,8-萘-乙炔化合物进行热异构化为[1,2- a ] py衍生物,并通过X射线分析建立了新的多环芳族体系的结构。异构化的机理通过依次通过双自由基中间体进行环化反应以及随后的氢迁移来解释。
