摘　　要：Polyfluoroalkyl iodides reacted with olefins in aqueous DMF solution of sodium disulfite under mild conditions to give the corresponding 1:1 adducts in good yields,providing a convenient polyfluoroalkylation method.This indicated that R_F radicals were formed in the reaction of polyfluoroalkyl iodides and sodium disulfite.A SET mechanism is proposed for the sulfinatodehalogenation reaction of sodium disulfite.Polyfluoroalkyl iodides reacted with olefins in aqueous DMF solution of sodium disulfite under mild conditions to give the corresponding 1:1 adducts in good yields,providing a convenient polyfluoroalkylation method.This indicated that R_F radicals were formed in the reaction of polyfluoroalkyl iodides and sodium disulfite.A SET mechanism is proposed for the sulfinatodehalogenation reaction of sodium disulfite.
