on Buchwald–Hartwig aminations. Using 1 mol% N‐heterocyclic carbene adduct of cyclopalladated ferrocenylimine in the presence of 1.5 equiv. tBuOK as base in dioxane at 110°C offered moderate to excellent yields in the reaction of chloropyridines with primary and secondaryamines, including sterically hindered amines and alkyl amines.
