抄録

Perfluoroalkyl-telluration of alkynes has been performed by a (PhTe)2–NaBH4–RfX system at a low temperature (−40, −80, or −100 °C) to give 2-(perfluoroalkyl)vinyl tellurides. Meanwhile, perfluoroalkyl-sulfenylation and perfluoroalkyl-selenation were less effective. The perfluoroalkyl-telluration proceeds mainly via both SRN1 process and photochemical addition of the in situ formed perfluoroalkyl phenyl telluride (RfTePh). The efficiency of the chalcogenolate anions for perfluoroalkyl-chalcogenation was found to be the order of PhS− < PhSe− < PhTe−.
