Under the influence of a manganese porphyrin/iodosylbenzene system, a variety of unactivated aliphatic C–H bonds can be selectively converted to C–18F bonds. The mild conditions, broad substrate scope and generally inaccessible regiochemistry make this radio-fluorination a powerful alternate to established nucleophilic substitution for the preparation of 18F labeled radio tracers.en-USSite-selective 18F fluorination of unactivated C–H bonds mediated by a manganese porphyrin† †Electronic supplementary information (ESI) available: Detailed experimental procedures and spectroscopic data for all new compounds.
