The sulfonamides CF3SO2N(CH3)Na and CF3SO2N(H)Na have been reacted with polyfluoro cyclic, acyclic and inorganic chlorine and bromine-containing species. Nucleophilic displacement of chlorine or bromine in 1,2-dichloroperfluorocyclobutene, 1,2-dichloroperfluorocyclopentene, benzyl bromide, cyanuric chloride and oxalyl chloride has been found to occur under mild conditions to give good yields of N-substituted
磺酰胺CF 3 SO 2 N(CH 3)Na和CF 3 SO 2 N(H)Na已与多氟环状,无环和无机氯和含溴物质反应。已发现在温和的条件下发生了在1,2-二氯全氟环丁烯,1,2-二氯全氟环戊烯,苄基溴,氰尿酰氯和草酰氯中的氯或溴的亲核取代反应,以产生良好收率的N-取代的多氟烷基和多氟芳基磺酰胺。讨论了溶剂和底物结构对反应发生必要条件的影响,以及所需产物的产率。
