Article abstract of DOI:10.1021/jo00281a027

Homo-coupling of aryl bromides and chlorides is efficiently performed with nickel-containing complex reducing agents NiCRA-bpy.In a number of cases the presence of alkali iodides improves the procedure.Yields are very high and a number of functional groups are resistant.The mechanistic and catalytic aspect of these reactions are discussed.
