Synthesis of 2-(fluorinated aryl)pyridine derivatives via palladium-catalyzed C–H bond arylation of fluorobenzenes using 2-halopyridines as aryl sources
Abstract : We report herein on palladium-catalyzed direct arylation of (poly)fluorobenzene derivatives in the presence of 2-halopyridines for the one-step synthesis of 2-[(poly)fluorinated aryl]pyridine derivatives. The reactivity of 2-bromopyridines strongly dependents on its substituents at C6 position. The reaction proceeds nicely using a diphosphine palladium catalyst, and potassium pivalate/dimethylacetamide (PivOK/DMA) as catalytic system. The reaction was regioselective and occurred at the ortho-position of fluorine atoms.
