symmetrical/unsymmetrical benzo[c]furans with acenaphthylene in xylenes at reflux temperatures followed by p-toluenesulfonic acid-mediated epoxide cleavage and dehydration furnished diaryl/heteroaryl-substituted benzo[k]fluoranthenes. This strategy could be successfully applied to the synthesis of dimeric and trimeric benzo[k]fluoranthenes. Functionalization of representative benzo[k]fluoranthene derivatives
在回流温度下,对称/不对称苯并 [c] 呋喃与苊在二甲苯中的 Diels-Alder 反应,然后是对甲苯磺酸介导的环氧化物裂解和脱水,得到二芳基/杂芳基取代的苯并 [k] 荧蒽。该策略可成功应用于二聚体和三聚体苯并[k]荧蒽的合成。还进行了代表性苯并[k]荧蒽衍生物的官能化。还报告了代表性荧蒽衍生物的紫外/可见光、发射和电化学性质。
