An efficient and mild copper-mediated reaction for the direct perfluoroalkylation and difluoromethylation of indoles with perfluoroalkyl halides and ICF2COOEt to produce 2-substituted indoles was developed. Both free indole derivatives and N-substituted indole derivatives could be used in this process to obtain the desired products in moderate to good yields.

An efficient process for the copper-catalyzeddirect perfluoroalkylation of C−H bonds in heteroarenes with commercially available perfluoroalkyl iodides is reported in this work. This reaction is based on a simple combination of copper(I) iodide and phenanthroline enabling the easy reduction of perfluoroalkyl iodides to the corresponding radical species that add to a wide range of heteroarenes.

of benzo- and dibenzo-(hetero)aromatic compounds without formal leaving groups is achieved efficiently in organic solvent: water mixtures under photostimulation. The methodology is compared to previously reported trifluoromethylation strategies of these nuclei in terms of product yields and regioselectivity. The global reaction is a radical homolytic aromaticsubstitution process, where the perfluoroalkyl-substituted
