โœฆ Synopsis

Perfluoroalkyl-chalcogenation of olefins has been performed by the reaction of chalcogenide anions with perfluoroalkylhalides (IV-X) in the presence of olefins. Chalcogenide anion cleaves reductively the carbon-halogen bond of Bf-X, generating perfluoroalkyl radicals which undergo addition to C=C bond. The intermediate perfluoroalkylated radicals(3) react with ArY-via Sml mechanism, propagating a chain reaction. The reactivity of the chalcogenide anion increases in the order of ArS

Perfluoroalkyl-selenation of olefins has been performed by the reaction of diphenyl diselenide with sodium borohydride followed with perfluoroalkyl halides (RfX) and olefins where one electron transfer from phenylseleno anion to RfX occurs, generating perfluoroalkyl and phenylseleno radicals.
