Mechanism of Lithium Diisopropylamide-Mediated Substitution of 2,6-Difluoropyridine

Treatment of 2,6-difluoropyridine with lithium diisopropylamide in THF solution at −78 °C effects ortholithiation quantitatively. Warming the solution to 0 °C converts the aryllithium to 2-fluoro-6-(diisopropylamino)pyridine. Rate studies reveal evidence of a reversal of the ortholithiation and a su...
