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