Novel isopropyl-substituted di- and tri-benzocyclo-octatetraenes are reduced to the corresponding dianions which, from their n.m.r. spectroscopic description, appear to be the first examples of conformationally mobile, ionic cyclo-octatetraene systems.
新颖的异丙基取代的二和三苯并环
辛酸酯被还原为相应的二价阴离子,从其nmr光谱描述来看,它们似乎是构象可移动的离子型环
辛酸酯系统的第一个实例。
