末端氟烯烃R_FCF=CF_2[R_F=CF_3,Cl(CF_2)2～4,H(CF_2)_4,n-C_3F_7O]与四氟乙磺内酯、氟化钾和卤素在二乙二醇二甲醚中反应,得到长链烷基醚磺酰氟[R_FCFXCF_2OCF_2CF_2SO_2F](1,2_a,b～6_a,b)。烯烃结构和反应温度对磺酰氟的产率有一定影响。用三氟化钴处理R_FCFXCF_2OCF_2CF_2SO_2F(5b,2b,8,9)时,—CF_2SO_2F失SO_2而转化为—CF_3,形成多氟醚(R_FCFXCF_2OCF_2CF_3)7及10～12。控制反应温度,二磺酰氟13也可以失去一个SO_2为主而形成单磺酰氟15。
The reaction of the terminal fluoroolefins R_FCF = CF_2 [R_F = CF_3, Cl (CF_2) 2 ~ 4, H (CF_2) _4, n-C_3F_7O] with tetrafluoroethane sultones, potassium fluoride and halogen in diethylene glycol dimethyl ether To obtain a long-chain alkyl ether sulfonyl fluoride [R_FCFXCF_2OCF_2CF_2SO_2F] (1,2_a, b_6_a, b). Olefin structure and reaction temperature have some influence on the yield of sulfonyl fluoride. When R_FCFXCF_2OCF_2CF_2SO_2F (5b, 2b, 8,9) is treated with cobalt (II) fluoride, -CF_2SO_2F is converted to -CF_3 by the loss of SO_2 to form polyfluoroether (R_FCFXCF_2OCF_2CF_3) 7 and 10-12. Controlling the reaction temperature, disulfonyl fluoride 13 can also lose one SO 2 and form monosulfonyl fluoride 15.
