91–99% yield. The reaction is selective for aliphatic monofluorides and can be coupled with in situ nucleophilic iodide replacements to install carbon–carbon, carbon–nitrogen, and carbon–sulfur bonds with high yields. Alkyl difluorides, trifluorides, even in activated benzylic positions, are inert under the same conditions and aryl fluoride bonds are also tolerated.
提出了一种使用廉价的碘化锂对各种活化和未活化脂肪族基材进行 C-F 键功能化的高效方法。伯、仲、叔、苄基、炔丙基和α-官能化烷基氟化物在氯化或芳香族溶剂中在室温或加热下反应生成相应的碘化物,其分离收率为91-99%。该反应对脂肪族一氟化物具有选择性,并且可以与原位亲核碘化物取代偶联,以高产率安装碳-碳、碳-氮和碳-硫键。烷基二氟化物、三氟化物,即使在活化的苄基位置,在相同条件下也是惰性的,并且也可以容忍芳基氟化物键。
