An air- and moisture-stable palladium catalyst, [(CyPF-Bu-t)PdCl2] (1), for coupling of heteroaryl chlorides, bromides, and iodides with a variety of primary amines is described. Most of these reactions occurred in high yield with 0.001-0.05 mol % catalyst loading. The reactions tolerated a wide range of functional groups.

We report a diverse demonstration of synthetically useful chemoselectivity in the synthesis of di-, tri-, and tetraamines (62 examples) by use of Buchwald–Hartwig amination employing a single catalyst system ([Pd(cinnamyl)Cl]2/L1; L1 = N-(2-(di(1-adamantyl)phosphino)phenyl)morpholine, Mor-DalPhos). Competition reactions established the following relative preference of this catalyst system for amine
