Site-selective 18F fluorination of unactivated C-H bonds mediated by a manganese porphyrin.

ABSTRACT: The first direct C-H 18F fluorination reaction of unactivated aliphatic sites using no-carrier-added [18F]fluoride is reported. 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.
