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.
