title: Palladium-catalyzed direct C-H arylation of pyridine N-oxides with potassium aryl- and heteroaryltrifluoroborates.
abstract: An efficient ligand-free Pd(OAc)2-catalyzed selective arylation of pyridine N-oxides using potassium (hetero)aryltrifluoroborates as coupling partners via C-H bond activation was achieved in the presence of TBAI. This approach has a broad substrate scope and shows moderate to high yields.
