The application of the modified Ullmann reaction to 2-chloro-3-trifluoromethylpyridine furnishes 5, 5′-bis (trifluoromethyl)-2, 2′-bipyridine as the primary product, accompanied by small amounts of the expected 3, 3′-bis (trifluoromethyl)-2, 2′-bipyridine, 2-benzyl-3- (trifluoromethyl) pyridine, bibenzyl, 3-trifluoromethylpyridine, 3-methylpyridine, 2- hydroxyethyl-(3-trifluoromethylpyridyl) ether and 2-hydroxyethyl-(3-methylpyridyl) ether. ...
