Reaction of perfluoroalkanesulfinates with allyl and propargyl halides. A convenient synthesis of 3-(perfluoroalkyl)prop-1-enes and 3-(perfluoroalkyl)allenes
摘要:
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.
