This paper report a convenient methodology for perfluoroalkylation including trifluoromethylation of (hetero)arenes with perfluoroalkyl bromides using a specific cobalt-based nanocatalyst.
perfluoroalkylation of organic compounds is reported. This operationally simple approach occurs under mild conditions producing valuable new C-C bonds. The chemistry is driven by the ability of NCNDs to directly reach an electronically excited state upon light absorption, thereby successively triggering the formation of reactive radical species from simple perfluoroalkyliodides.

Perfluoroalkylation of various aromaticcompounds with perfluoroalkylphenyliodonium trifluoromethanesulfonate (FITS) under mild conditions was described. The reactivity of other perfluoroalkyliodonium salts was also examined.
A new method of single-stage synthesis of perfluoroalkylated arenes via cross-coupling of bromo (in some cases, chloro) arenes and heteroarenes (derivatives of benzene, pyridine and furan) and organic perfluoroalkyl halides involving complexes of nickel and cobalt in low oxidation state with α-diimines under mild conditions was proposed. Perfluoroalkylated products are obtained in good yields in the
