  • Title: Palladium-catalyzed coupling of hydroxylamines with aryl bromides, chlorides, and iodides.
    Author: Porzelle A, Woodrow MD, Tomkinson NC.
    Journal: Org Lett; 2009 Jan 01; 11(1):233-6. PubMed ID: 19035839.
    Abstract:
    The bis-pyrazole phosphine ligand BippyPhos is effective for the palladium-catalyzed cross-coupling of hydroxylamines with aryl bromides, chlorides, and iodides. Reactions proceed smoothly at 80 degrees C in toluene in the presence of Cs(2)CO(3) to give synthetically versatile N-arylhydroxylamine products in good to excellent yield.
