Abstract

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.
