An iron-catalyzed C-C bond formation reaction of a nitrogencontaining aromatic compound with an arylzinc reagent takes place at 0 degrees C in a good to quantitative yield. The reaction involves a C-H bond activation directed by a neighboring nitrogen atom. The important additives in this reaction are 1,10-phenanthroline, tetramethylethylenediamine, and 1,2-dichloro2-methylpropane, in the absence of which a very low product yield was observed.
