A highly selective C–H functionalization of nitrobenzenes and nitropyridines is reported using tandem vicarious nucleophilic substitution (VNS) chemistry with electrophilic fluorination using Selectfluor®. The process generates tertiary benzylic fluorides in good yield under simple, mild conditions and short reaction times.
