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‐coupling reactions proceed at the aryl bromide moiety with 69–98 % yields with expected tolerance of the SO2F group towards the coupling reaction conditions.
制备了在杂环的各个位置带有Br原子的五元和六元杂芳族磺酰氟。化学选择性的Suzuki,Stille和Negishi sp 2 –sp 2或sp 2 –sp 3 C–C交叉偶联反应在芳基溴化物部分进行,产率为69–98%,SO 2 F基团对偶联反应的预期耐受性条件。
