2,2′-Bipyridyls have been utilized as indispensable ligands in metal-catalyzed reactions. The most streamlined approach for the synthesis of 2,2′-bipyridyls is the dehydrogenative dimerization of unfunctionalized pyridine. Herein, we report on the palladium-catalyzed dehydrogenative synthesis of 2,2′-bipyridyl derivatives The Pd catalysis effectively works with an AgI salt as the oxidant in the presence of pivalic acid. A variety of pyridines regioselectively react at the C2-positions. This dimerization method is applicable for challenging substrates such as sterically hindered 3-substituted pyridines, where the pyridines regioselectively react at the C2-position. This reaction enables the concise synthesis of twisted 3,3′-disubstituted-2,2′-bipyridyls as an underdeveloped class of ligands. In addition to this study using 4,4′-Dimethyl-2,2′-bipyridine, there are many other studies that have used 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Safety of 4,4′-Dimethyl-2,2′-bipyridine) was used in this study.
4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6) is used in the synthesis of a series of o-phenanthroline-substituted ruthenium(II) complexes.Safety of 4,4′-Dimethyl-2,2′-bipyridine Furthermore, 4,4′-Dimethyl-2,2′-bipyridine is used as a chemical Intermediate. It can be used for the determination of ferrous and cyanide compounds.
