The reaction of polychloroiodoarenes with copper in dimethylformamide gives good yields of the biaryls. 4Bromotetrachloropyridine gives products of halogen exchange and reduction as well as coupling. Pentachloropyridine gave only tetrachloropyridines. Evidence against free radical or pyridyne intermediates is presented, and it is postulated that the reactions proceed via pyridylcopper compounds, although
