C−F Insertion reactions represent a powerful approach to prepare complex fluorinated compounds, yet they are extremely scarce. Here we report a hydrogen bonding-mediated system that allows for activation of activated alkyl fluorides without sequestering the released fluoride in an unreactive by-product. This allows for formal insertion of fluorinated styrenes into the C−F bond affording gem-difluorinated
C−F 插入反应代表了一种制备复杂
氟化化合物的有效方法,但它们极为稀缺。在这里,我们报告了一种氢键介导的系统,该系统允许激活活化的烷基
氟化物,而不会将释放的
氟化物隔离在非反应性副产物中。这允许将
