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.

Palladium-catalyzed direct CH bond arylation of simple arenes with aryltrimethylsilanes

Direct CH bond arylation of arenes with aryltrimethylsilanes catalyzed by PdCl2 in the presence of CuCl2 as an oxidant has been developed. In addition to the role as the oxidant, CuCl2 is found to be necessary for the selective crosscoupling 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.

Selective transformations of phenylated diynes to polycyclic compounds by the RhCl3- and PtCl4-Aliquat 336 ion pair catalysts

The ion pairs generated from methyltricaprylammonium chloride and either RhCl3 or PtCl4 catalyze, under phase transfer conditions, selective cyclorearrangements, as well as intra- and intermolecular addition processes by which discre

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.
