Herein we disclose a deoxyfluorination of alcohols with an electrophilic fluorine source via visible-light photoredox catalysis. This radical-mediated C–F coupling is capable of fluorinating secondary and tertiary alcohols efficiently, complementing previously reported nucleophilic deoxyfluorination protocols.

transformation have used bench‐stable fluorine atom sources; however, many still rely on the use of UV‐active photocatalysts for the requisite high‐energy hydrogenatomabstraction event. Uranyl nitrate hexahydrate is described as a convenient, hydrogenatomabstraction catalyst that can mediate fluorinations of certain alkanes upon activation with visiblelight.
