and six‐membered heteroaromatic sulfonyl fluorides bearing the Br atom at various positions of the heterocyclic ring were prepared. Chemoselective Suzuki, Stille, and Negishi sp2–sp2 or sp2–sp3 C–C cross‐couplingreactions proceed at the aryl bromide moiety with 69–98 % yields with expected tolerance of the SO2F group towards the couplingreaction conditions.
