- A synthetic strategy to access 2,6-disubstituted pyridines from triazolopyridines through a regioselective nickel-catalyzed alkenylation reaction of the C7–H bond is described. The N₂ fragment embedded in the resulting C–H functionalized triazolopyridine can be readily excised using acidic or oxidative conditions to unmask the pyridine.
