METHOD FOR PRODUCING POLYCYCLIC AROMATIC COMPOUND SUBSTITUTED BY ARYL GROUP

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.

Direct arylation of polycyclic aromatic hydrocarbons through palladium catalysis

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.

The 2?s + 2?s Photocycloadditions of Triplet Pyrene to Cyclohexa-1,3-diene

exo-(8bSR,8cSR,12bRS,12aSR)-8b,8c,11,12,12a,12b-Hexahydrobenzocyclobutapyrene and endo-(8bSR,8cSR,12bRS,12aRS)-8b,8c,11,12,12a,12b-hexahydrobenzocyclobutapyrene have been isolated; this is the first example of a 2?s + 2?s photocycloaddition between cyclohexa-1,3-diene and 3pyrene.
