  • Title: Palladium-catalyzed borylation of phenyl bromides and application in one-pot Suzuki-Miyaura biphenyl synthesis.
    Author: Broutin PE, Cerna I, Campaniello M, Leroux F, Colobert F.
    Journal: Org Lett; 2004 Nov 25; 6(24):4419-22. PubMed ID: 15548040.
    Abstract:
    The coupling reaction of pinacolborane with various aryl bromides in the presence of a catalytic amount of Pd(OAc)(2) together with DPEphos as ligand and Et(3)N as base provided arylboronates. High yields were obtained in the case of electron-donor substituted aryl bromides. The direct preparation of arylboronates allowed the one-pot, two-step synthesis of unsymmetrical biaryls in high yields. [reaction: see text]
