In a ligand-free chromium(II)-catalyzed amination reaction of various N-heterocyclic chlorides, CrCl2 regioselectively catalyzes the reaction of chloropyridines, chloroquinolines, chloroisoquinolines, and chloroquinoxalines with a broad range of magnesium amides in the presence of lithium chloride as additive. The reactionse provide the desired aminated products in good yield.
