Methods that can directly arylate pyridines have significant potential in synthetic chemistry. Herein, we present palladium catalyzed C-H arylation of pyridines with aryl triflates that occurs regioselectively at the C3 positions of the pyridine core. A variety of aryl triflates and pyridines were applicable to the reaction to provide C3-arylated pyridines regardless of sterics or electronics of the pyridine cores.
