An Attempted Synthesis of 8-Shaped Circulene: Synthesis and Characterization of [2.2](4,4<sup>′</sup>)Biphenylo(3,11)dibenzo[<b><i>c</i></b>,<b><i>l</i></b>]chrysenophane and Its Cyclophadiene
The syntheses of the title compounds are described. The unusually strained structures were supported by their 1H NMR spectra, electronic spectra, and X-ray crystallographic analyses.
描述了标题化合物的合成。1H NMR 光谱、电子光谱和 X 射线晶体学分析支持了异常应变的结构。
