bicyclo[4.2.1]nona-2,4,7-triene (9, 11, and 14) and 9-substituted barbaralane (10, 12, and 15). In the case of 8, products containing two nitrogen atoms (17 and 18) were isolated. The structure and the photochemical reaction of 17 provided strong support for the intermediacy of the tetracyclo[4.3.0.02,9.05,7]-nona-3-ene (37) derivative for the formation of the bicyclo[4.2.1]nona-2,4,7-triene derivatives
(2,4,6-环庚三烯-1-基)乙醛甲苯磺酰腙(4、6和8)的钠盐的热分解得到9-取代的双环[4.2.1]壬二烯-2,4,7-三烯( 9、11 和 14) 和 9-取代的巴巴拉烷 (10、12 和 15)。在 8 的情况下,分离出含有两个氮原子(17 和 18)的产物。17的结构和光化学反应为四环[4.3.0.02,9.05,7]-nona-3-ene(37)衍生物的中间体形成双环[4.2.1]nona-2提供了强有力的支持,4,7-三烯衍生物。讨论了 C9H10 和 C10H10 烃之间能量表面的差异。
