Palladium(III)-Catalyzed Fluorination of Arylboronic Acid Derivatives

A practical, palladium-catalyzed synthesis of aryl fluorides from arylboronic acid derivatives is presented. The reaction is operationally simple and amenable to multigram-scale synthesis. Evaluation of the reaction mechanism suggests a single-electron-transfer pathway, involving a Pd­(III) intermediate that has been isolated and characterized.
