We have discovered that the combination of Pd(OAc)(2)/o-chloranil can catalyze the direct C-H bond arylation of polycyclic aromatic hydrocarbons (PAHs) with arylboroxins that occurs selectively at the K-region. The sequential integration of Pd-catalyzed direct arylation of PAHs and FeCl(3)-mediated cyclodehydrogenation is effective in rapidly extending a parent PAH π-system with high directionality.
我们发现,Pd(OAc)(2)/邻氯过氧苯甲酰可以催化多环芳烃(PAHs)与芳基硼酸的直接 C-H 键芳基化反应,该反应选择性地发生在 K-区域。Pd 催化的 PAHs 直接芳基化反应和 FeCl(3)介导的环脱氢反应的顺序集成,有效地以高方向性快速扩展母体 PAH π-体系。
