Abstract: The palladium-catalyzed amination of aryl halides(Buchwald-Hartwig amination) is a rapidly developing field due to the importance of the products in many fields, e.g. pharmaceuticals, xerography, electronic materials and ligands for transition metals. In this article, a novel cyclopalladated ferrocenylimine carbene complex 3 was conveniently synthesized and characterized via IR, ¹H NMR, ¹³C NMR, HRMS and X-ray single crystal diffraction. Compound 3 was stable to air and moisture in both the solid state and solution. It was successfully applied for the Buchwald-Hartwig amination of aryl chlorides. Using 0.5%(molar fraction) of catalyst 3, in the presence of 2 equiv of ^tBuOK as a base in dioxane at 110 ℃ for 3 h, a variety of aryl chlorides and amines could be coupled to afford the coupled products in moderate or excellent yields.

Key words: Cycllopalladated ferrocenylimine, N-Heterocyclic carbene, Amination, Aryl chlorides
