  • Title: Synthesis of dibenzofurans directly from aryl halides and ortho-bromophenols via one-pot consecutive SNAr and intramolecular palladium-catalyzed aryl-aryl coupling reactions.
    Author: Xu H, Fan LL.
    Journal: Chem Pharm Bull (Tokyo); 2008 Oct; 56(10):1496-8. PubMed ID: 18827400.
    Abstract:
    A series of dibenzofurans were efficiently and conveniently synthesized via one-pot consecutive C(sp(2))-O bond formation reaction (SNAr) in the presence of anhydrous K(2)CO(3), followed by C(sp(2))-C(sp(2)) bond formation reaction (intramolecular palladium-catalyzed aryl-aryl coupling reaction) between aryl halides and ortho-bromophenols. The desired dibenzofurans were obtained in 32-99% isolated yields.
