PAH is subjected to C-H/C-B coupling using a specific boron compound, a palladium compound, and o-chloranil to produce a compound in which a C-H bond of the PAH is directly arylated regioselectively in a simple manner. When the substrate and the boron compound are appropriately selected, a larger PAH can also be obtained by further performing an annulation reaction after the coupling reaction. Similarly, when PAH is subjected to C-H/C-H cross-coupling using a specific aromatic compound, a palladium compound, and o-chloranil, a compound in which a C-H bond of the PAH is directly arylated regioselectively can be produced in a simple manner. When the substrate and the aromatic compound are appropriately selected in this case, a larger PAH can also be obtained by further performing an annulation reaction after the cross-coupling reaction.
使用特定的硼化合物、钯化合物和邻氯苯胺对 PAH 进行 C-H/C-B 偶联,可生成一种化合物,其中 PAH 的一个 C-H 键以简单的方式直接进行了区域选择性芳基化。如果底物和硼化合物选择得当,还可以在偶联反应后进一步进行环化反应,从而获得更大的 PAH。同样,当使用特定的芳香族化合物、钯化合物和邻氯苯胺对 PAH 进行 C-H/C-H 交叉偶联反应时,也能以简单的方式制得 PAH 的 C-H 键直接芳基化的化合物。在这种情况下,如果底物和芳香族化合物选择得当,还可以在交叉偶联反应后进一步进行环化反应,得到更大的多环芳烃。
