Sequential reaction cascades for the synthesis of polysubstituted 2‐ and 3‐fluoropyrrole derivatives from common polybromopyrrole precursors have been developed. A strategic variation of a combination of regioselective debromolithiation followed by trapping of the corresponding carbanions by electrophilic fluorination and Pd catalysed cross coupling reactions allows access to polyfunctional fluoropyrrole
