A highly active catalyst system derived from PdCl2 and 2,2',6,6'- tetramethoxy-4,4'-bis(diphenylphosphanyl)-3,3'-bi- pyridine (P-Phos) has been developed for the Suzuki cross- coupling reaction of pyridylboronic acid with a variety of aryl halides in good to excellent yields, even in the presence of hindered and functional groups. In addition, P-Phos also exhibited high activity in the palladium-catalyzed Suzuki reaction of 2,6-dimethoxypyridylboronic acid in excellent yields with a fast rate. The steric and electronic effects of the P- Phos-palladium complex to this cross-coupling reaction were also discussed.
