The preparation and properties of polyfluoro aromatic and heteroaromatic compounds
TL;DR: In this paper, a review of the chemical behaviour of polyfluoro aromatic and heteroaromatic compounds, at the fluorinated ring, forms the major proportion of this review: reactions with nucleophiles and a rationalisation of orientation reactions; reactions with electrophiles, free radicals, carbenes and nitrenes; the formation of stable salts of radical cations; photochemical reactions and the formationof valence isomers; and rearrangement reactions.

Some new aspects in the application of perfluoroalkyl halides in the synthesis of fluorine-containing organic compounds
TL;DR: In this article, the authors considered the activation of perfluoroalkyl halides used as intermediates in the synthesis of partially fluorinated compounds, and the conditions for reactions of organic compounds with perfluoralkyl iodides in the presence of reductants (Na2S2O4, HOCH2SO2Na), metals and metal salts, redox systems (Na 2S2 O8, ButOOH, Pb(OAc)4, H2O2-FeSO4, Ce(SO4)2) and transition metal
