difluoroenoxysilanes is developed. This procedure enables the synthesis of a broad range of α,α-difluoroketones, a class of highly valuable intermediates and building blocks in medicinal and organic chemistry. Here, we have demonstrated for the first time that HFIP could act as a powerful catalyst for fluorinated carbon–carbon bond formation. The application of this protocol in late-stage dehydroxydifluoroalkylation
开发了六氟异丙醇(HFIP)催化的苄基和烯丙基醇与二氟烯氧基硅烷的直接脱羟基二氟烷基化反应。该方法可以合成多种α,α-二氟酮,一类非常有价值的中间体以及医药和有机化学的基础材料。在这里,我们首次证明了HFIP可以作为形成氟化碳-碳键的有力催化剂。该方案在潜在的生物活性药物和天然产物的后期脱羟基二氟烷基化反应中的应用也已进行。
