The reaction of perfluoroalkanesulfinates, R(f)CF2SO2Na, with allyl and propargyl halides, in the presence of (NH4)2S2O8, gave 3-(perfluoroalkyl)prop-1-enes (R(f)CH2CH = CH2) and 3-(perfluoroalkyl)allenes (R(f)CH = C = CH2), respectively, in good yield. Evidence is presented for a radical addition-elimination mechanism for the reaction. The reaction represents a synthetically viable and convenient route to such compounds.

C-radical addition to the double bond of the title reagents and subsequent base-promoted homolytic Cα–Cβ cleavage leads to the formation of the corresponding allylated products along with ketyl radicals that act as single electron reductants to sustain the chain reactions. Substrate scope is documented and the role of base in the C–Cbond activation is studied by computation.
