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