A mild and practical method for synthesizing fluorinated quinoline derivatives, which have a wide range of applications in pharmaceuticals, materials, and organic synthesis, was described through C—F bond insertion into indoles using CHBr₂F. The simple conditions, readily availability of CHBr₂F, as well as the versatility of the transformations make this strategy very powerful in synthesizing 3-fluoroquinoline and 3-fluoroquinolone. More details are discussed in the article by Song et al. on page 1128—1132.
