The title compound, an example of a hydrocarbon containing three linearly fused 4n-membered rings, has been synthesized and characterized as a thermally stable species possessing no unusual chemical reactivity. Despite the presence of these conventionally antiaromatic structural units this hydrocarbon is predicted to have a net diamagnetic ring current. The NMR results, which are discussed in some
标题化合物是含有三个线性稠合4n元环的烃的实例,已合成并表征为不具有异常
化学反应性的热稳定物质。尽管存在这些常规的抗芳族结构单元,但仍预测该烃具有净反磁环电流。NMR结果(对此进行了详细讨论)表明与该预期是一致的。简要讨论了该结果对NMR芳香性标准的影响。
