Synthesis of Arylstannanes via Palladium‐Catalyzed Decarbonylative Coupling of Aroyl Fluorides

Aryl stannanes are valuable precursors in organic transformations, but their synthetic methods are limited. Here we present a Pd‐catalyzed decarbonylative stannylation of acid fluorides in the absence of exogenous base. Various aryl stannanes were efficiently prepared from bench‐stable transition metal catalyst and ligand with broad functional group compatibility and substrate scope including natural products and pharmaceuticals. This protocol was also successfully used to a late‐stage diversification of an existing uricosuric drug probenecid.
