NN-Bistrifluoromethylethynylamine, (CF3)2N·C⋮CH, has been prepared in high yield by the reaction of N-bromobistrifluoromethylamine with acetylene, followed by dehydrobromination of the resultant 1 : 1-adduct, 2-bromo-NN-bistrifluoromethylvinylamine. The bromination of bistrifluoromethylvinylamine to give 1,2-dibromo-NN-bistrifluoromethylethylamine and the dehydrobromination of this adduct, by way of
NN -Bistrifluoromethylethynylamine,(CF 3)2 N·Ç⋮CH,已在通过反应高产率制备Ñ -bromobistrifluoromethylamine与乙炔,然后将所得1的脱溴化氢:1加合物,2-溴- NN -bistrifluoromethylvinylamine 。的bistrifluoromethylvinylamine溴化以得到1,2-二溴- NN -bistrifluoromethylethylamine和这种加合物的脱溴化氢,由烯烃1-溴方式NN -双trifluoromethylvinylamine,也给出了乙炔。Ñ与-Bromobistrifluoromethylamine发生反应NN -bistrifluoromethylethynylamine,得到1,2-二(bistrifluoromethylamino)-1-溴乙烯,(CF3) 2
