Regioselective Syntheses of Substituted Pyridines and 2,2′-Bipyridines by Cobalt-Catalyzed [2+2+2] Cycloaddition of α,ω-Diynes with Nitriles

On page 2248, second column, line 6: ”3-alkynylpyridines or 3-(2-pyridyl)pyridines 4" should be ”2-alkynylpyridines or 2-(2-pyridyl)pyridines 3". In the title of Table 1, ”R = Me" should be ”R^³ = Me", and in Table 4, the column heading ”R^²" should be ”R^¹".
