In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Dehydrogenative Synthesis of 2,2′-Bipyridyls through Regioselective Pyridine Dimerization, published in 2019, which mentions a compound: 1762-34-1, mainly applied to pyridine palladium catalyst regioselective dimerization dehydrogenative silver pivalic acid; bipyridyl preparation; 2,2′-bipyridyls; C−H arylation; dehydrogenative coupling; palladium; pyridines, Safety of 5,5′-Dimethyl-2,2′-bipyridine.
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.
