A number of nitrogen, sulfur or oxygen containing bis-heteroaromatic or bis-heterocyclic derivatives have been synthesized in good to excellent yields by homo-coupling of the corresponding halogenated compounds in the presence of liganded (triphenylphospine or 2,2'-bipyridine) nickel Complex Reducing Agents in THF or DME at 63 degrees C.
