Synthesis of Pyridine-<i>N</i>-oxide–Borane Intramolecular Complexes by Palladium-Catalyzed Reaction of 2-Bromopyridine-<i>N</i>-oxides with Alkynyltriarylborates
Pyridine-N-oxide-borane Intramolecular complexes having an aza-stilbene pi-framework were synthesized by the palladium-catalyzed reaction of 2-bromopyridine-N-oxides with alkynyltriarylborates.
