The direct cross-coupling of heterocyclic phosphonium salts with aryl bromides was successfully realized by performing the reactions in THF at ambient temperature with the aid of a nickel(II) catalyst, the 1,10-phenanthroline-5,6-dione ligand, magnesium turnings, and lithium chloride, providing an easy access to 4-arylated pyridine, quinoline, quinoxaline, and pyrazine.
