Abstract
Abstract A protocol for an efficient, modified Negishi cross-coupling strategy for substituted 2, 2′-bipyridines employing tetrakis (triphenylphosphine) palladium (0) as a simple, commercially available, and relatively inexpensive catalyst for both 2-bromo-and 2- chloropyridines has been developed. Further transformations were carried out yielding some new valuable functionalized 2, 2′-bipyridines.
