A nickel(I) dimer catalyzes the chemoselective trifluoromethylselenolation of aryl iodides, and computational and experimental reactivity data suggest dinuclear NiI catalysis to be operative. The corresponding Ni0 species, on the other hand, suffers from preferred reaction with the product, ArSeCF3, over productive cross-coupling and is hence inactive.

Hemiaminals of fluoral and derivatives have been previously described as efficient new reagents for the nucleophilic trifluoromethylation of carbonyl compounds. Their use has been extended to the synthesis of trifluoromethyl sulfides and selenides fromdisulfides and diselenides.

perfluoroalkyl selenoxides, selenones and selenoximines was possible through a selective oxidation of perfluoroalkyl selenoethers. Synthesis of perfluoroalkyl selenoxides was also described via a two-step one-pot reaction from selenocyanates. The perfluoroalkyl selenoximine family was synthesized. The Hansch-Leo parameters of the compounds were determined and some aryl perfluoroalkyl selenoxides were separated

This paper describes an electrochemical nickel-catalyzed reaction of trifluoromethylselenolation of various aryl iodides, catalytic in electron, and using [Me4N]+[SeCF3]− as reagent. A Ni(0)-based catalytic cycle was proposed on the basis on electrochemical investigations.
