perfect C8 regioselectivity and a wide functional group tolerance. In most cases, the desired polyaromatic compounds were isolated in good to excellent yields. To explain the observed regioselectivity, DFT calculations were performed and highlighted the crucial role of the amide directing group. Finally, the utility of this method is showcased by the synthesis of benzanthrone derivatives.
在此,描述了1-ami萘的直接C8-芳基化反应。通过使用二芳基碘鎓盐作为芳基化剂,钯催化的CH活化反应显示出完美的C8区域选择性和宽泛的官能团耐受性。在大多数情况下,所需的聚芳族化合物以良好至极好的收率被分离出来。为了解释观察到的区域选择性,进行了DFT计算并强调了酰胺导向基团的关键作用。最后,苯并蒽醌衍生物的合成证明了该方法的实用性。
