Upon flash vacuum thermolysis at 750 °C fluorenylidenecyclopropa[b]naphthalene (1) undergoes opening of the three-membered ring and rearrangement to give a range of C24H14 polycyclic aromatic hydrocarbons. Dibenz[e.l]- and -[e.k]acephenanthrylene (7) and (12), respectively, have been identified while the plausible naphth[1,2-e]- and [2,3-e]acephenanthrylenes (9) and (14) were not detected. With di
在750℃下的闪蒸真空热解中,亚芴基亚环丙烷[ b ]萘(1)经历三元环的开环并重排,得到一系列C 24 H 14多环芳烃。Dibenz [ e。l ]-和-[ e。已分别鉴定出k ]对苯二甲苯(7)和(12),而未检测到可能的萘[1,2- e ]-和[2,3- e ]对苯二酚(9)和(14)。与二苯基亚甲基环丙烷[ b ]萘(2)环脱氢和重排也提供C 24 H 14多环;dibenz [ e。k ]对苯乙(12)被鉴定和dibenz [ a。e ]乙炔(15)是一种提议的产品。
