全氟烷基磺酰氟和磺酰氯的化学已有广泛的研究,对于全氟烷基磺酰溴则直到最近才有较为详尽的工作,但迄今尚未见有关全氟烷基磺酰碘的报道.芳基磺酰碘比较稳定,并可分离鉴定,但烷基磺酰碘需在反应前制备,而又未能分离纯化.企图制备三氯甲基磺酰碘或一氯甲烷基磺酰碘都未实现.我们曾采用类似于制备全氟烷基磺酰溴的方法,将全氟烷基亚磺酸钠与 I_2-KI 水溶液或 Perfluoroalkyl sulfonyl fluoride and sulfonyl chloride chemistry has been extensively studied, and perfluoroalkyl sulfonyl bromides have not been more detailed until recently, but no reports of perfluoroalkyl sulfonyl iodides have so far been reported Arylsulfonyl iodide is relatively stable and can be isolated and identified, but alkyl sulfonyl iodide need to be prepared before the reaction, but failed to separate and purify.In an attempt to prepare trichloromethylsulfonyl iodide or monochloromethylsulfonyl iodide We have used a method similar to the preparation of perfluoroalkylsulfonyl bromide, sodium perfluoroalkyl sulfinate and I_2-KI aqueous solution or
