Double-cross-coupling of dibromo arenes with aryltriolborates was carried out in the presence of a palladium catalyst such as Pd(OAc)2, Pd(PPh3)4 or Pd(OAc)2/BIPHEP. The use of CuCl (40 mol %) with a palladium catalyst was found to be highly effective to give diaryl-substituted aromatic compounds in good yields.ElsevierJournal Articleapplication/pdfhttp://hdl.handle.net/2115/47212https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/47212/1/Tet67-36_6804-6811.pdf0040-4020Tetrahedron6736680468112011-09-09enginfo:doi/10.1016/j.tet.2011.06.083author
