NN-Bistrifluoromethylvinylamine, prepared in high yield by the dehydrohalogenation of 2-iodo- or 2-bromo-NN-bistrifluoromethylethylamine, reacts with hydrogen bromide or with N-bromobistrifluoromethylamine in the dark to give 1-bromo-NN-bistrifluoromethylethylamine or 1,1-di(bistrifluoromethylamino)-2-bromoethane, respectively, which indicates that the olefin is polarised in the sense (CF3)2N·[graphic
NN -Bistrifluoromethylvinylamine,通过2-碘-或2-溴-脱卤化氢以高收率制备NN -bistrifluoromethylethylamine,与溴化氢或具有发生反应ñ -bromobistrifluoromethylamine在黑暗中以得到1-溴NN -bistrifluoromethylethylamine或1,1- -二(双三氟甲基氨基)-2-溴乙烷,分别表示烯烃在(CF 3)2 N·[省略图示]的意义上被极化。在有助于形成自由基中间体的条件下,相同反应物的产物为2-溴-NN-双三氟甲基乙胺和1,2-二(双三氟甲基氨基)-1-溴乙烷。异构体1:1加合物[(CF 3)2 N] 2 CH·CH 2 Br和(CF 3)2 N·CHBr·CH 2 ·N(CF 3)2的脱氢溴化反应以良好的产率得到相应的烯烃。当暴露于紫外线下时,溴化氢与1,1-二(双三氟甲基氨基)
