【摘要】 <正> 前已报道ω-碘-3-氧杂全氟烷磺酰氟(1a～c)与乙烯的自由基加成反应。我们发现用过氧化叔丁基、偶氮二异丁腈、过氧化苯甲酰为引发剂,均能使1与烯丙醇、乙酸烯丙酯、烯丙基乙基醚、正辛烯-[1]、丙炔醇顺利地进行加成,得到加成物2～6.1a,b与苯反应,用过氧化叔丁基引发的转化率低、产物较复杂。只有在约等摩尔过氧化苯甲酰时,才更多还原

【Abstract】 The compounds XCH₂CHICH₂（CF₂）_2nO（CF₂）₂SO₂F (2, X=OH; 3, X=OAc; 4,X=OEt; 5, X=n-C₅H₁₁) and HOCH₂CHI=CH（CE₂）₂O（CF₂）₂SO₂F （6a） were syn-thesized by free radical addition of ω-iodo-3-oxaperfluoroalkane sulfonyl fluoridesI（CF₂）_2nO（CF₂）₂SO₂F（1a～c, n=1～3） wiih allyl alcohol, allyl acetate, allyl ethylether, octene-[1] and propargyl alcohol respectively using peroxides as initiators.1a also reacted with benzoyl peroxide in benzene to give the corresponding ω-phenylderivatives 7a, b. Compounds 2, 3 and 4 reacted with zinc in isopropanol to giveCH₂=CHCH₂（CF₂）_2nO（CF₂）₂SO₂F （8） in good yield. When a small amount of aceticacid was added to the reaction mixture the reaction time required was shorten andthe yield was improved significantly. On the other hand, 5a and 6a was reduced byzinc to give 9a and 10a respectively.更多还原
