  • Title: A facile one-pot preparation of potassium hydroxyaryl- and (hydroxyalkyl)aryltrifluoroborates.

    Journal: Org Lett; 2008 Mar 20; 10(6):1215-8. PubMed ID: 18293993.
    Abstract:
    Potassium hydroxyaryl- and (hydroxyalkyl)aryltrifluoroborates have been prepared in a simple one-pot process from the corresponding hydroxy-substituted aryl halides in 51-98% yields through an in situ protection of the free hydroxyl group with t-BuLi. Also, we successfully performed a microwave-promoted Suzuki-Miyaura cross-coupling reaction of these substrates with aryl- and alkenyl bromides in the presence of 0.5 mol % of Pd(OAc)2 catalyst without ligands.
