The ability of α-borylated naphthalene-based aromatic compounds is important because it provides ready access to interesting novel extended π-systems. In this report, we disclose the Ni-catalyzed α-selective C-H borylations of naphthalene-based aromatic c

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.

Pd(OAc)2/o-chloranil/M(OTf)n can effectively promote the C-H arylation of fluoranthene with arylboron compounds or arylsilanes. The reaction takes place with high regioselectivity at the C3 position of fluoranthene. Moreover, the new

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.
Synthesis of fluoranthenes by hydroarylation of alkynes catalyzed by gold(I) or gallium trichloride

Electrophilic gold(I) catalyst 6 competes with GaCl3 as the catalyst of choice in the synthesis of fluoranthenes by intramolecular hydroarylation of alkynes. The potential of this catalyst for the preparation of polyarenes is illustrated by a s

, p. 1464 - 1466 (2008/12/21)
Direct C-H bond arylation of simple arenes with aryltin reagents has been successfully catalysed by PdCl2 in the presence of CuCl2. CuCl2 proved to be an activator for a palladium intermediate as well as an oxidant. The Royal Society of Chemistry.
