Fluorination reaction of alkenes with iodine and HF·pyridine complex (pyr·9HF) was performed under mild conditions in the presence of K₂S₂O₈ or Na₂S₂O₈ as an oxidant. Aliphatic and aromatic alkenes underwent iodofluorination to give the iodofluorinated products with high regioselectivity. The substitution reactions of the iodofluorinated product by nitrogen, sulfur, and oxygen nucleophiles indicated further applications as a building block for synthesis of 2-fluoroalkyl-substituted compounds.

用 HF 试剂碘介导的烯烃氟化：2-氟烷基碘化物的区域选择性合成

在K ₂ S ₂ O ₈或Na ₂ S ₂ O ₈氧化剂存在下，烯烃与碘和HF·吡啶络合物(pyr·9HF)的氟化反应在温和条件下进行。脂肪族和芳香族烯烃经过碘氟化反应得到具有高区域选择性的碘氟化产物。氮、硫和氧亲核试剂对碘氟化产物的取代反应表明其进一步用作合成 2-氟烷基取代化合物的构建单元。
