tropyliophanes 26a (tetrafluoroborate) and 26b (perchlorate). With acetone, 26a furnished trapping product 27, which underwent a homo-Diels–Alder addition with tetracyanoethylene to afford adduct 29. All new compounds were characterized by their spectroscopic and analytical data and for most – including 17 and 26b – the structures were also determined by X-ray diffraction.(© Wiley-VCH Verlag GmbH &
Tropylidenes 16 和 17 由 [2.2] 对环芳烷 (10) 制备。在用相应的三苯甲基盐处理后,它们被转化为托苯二酚 26a(四氟硼酸盐)和 26b(高氯酸盐)。使用丙酮,26a 提供捕集产物 27,该产物与四氰基乙烯进行均质-Diels-Alder 加成得到加合物 29。所有新化合物都通过其光谱和分析数据进行表征,并且对于大多数(包括 17 和 26b)结构也已确定通过 X 射线衍射。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
