Bis (heptafluorobutyry) peroxide reacted with electron-rich olefins to give the adducts of C3F7CO2 and C3F7 groups in good yields. The peroxide should be the useful reagent for the introduction of heptafluoropropyl moiety into olefins.
Treatment of α,β-unsaturatedketones and fluoroalkyl halides with Et2Zn in the presence of RhCl(PPh3)3 gave novel reductive fluoroalkylation products at the α-position of α,β-unsaturatedketones in moderate to good yields. The rhodium hydride complex derived from Et2Zn and Rh catalyst seems to have played an important role in this reaction.
