NN-bistrifluoromethylethynylamine with alkaline hypobromite. Bromo-NN-bistrifluoromethylethynylamine reacts with hydrogen bromide in the dark to give only cis-1,2-dibromo-NN-bistrifluoromethylvinyl-amine. The acid-catalysed hydration of NN-bistrifluoromethylethynylamine gives NN-bistrifluoromethylacetamide and hydrogenation yields NN-bistrifluoromethylvinylamine. NN-Bistrifluoromethylethynylamine does not react with
NN与溴化氢或在黑暗溴-Bistrifluoromethylethynylamine反应,得到1-溴NN -Bistrifluoromethylvinylamine或反式-1,2-二溴NN -bistrifluoromethylvinylamine,分别。在光解条件下,产物分别是顺式和反式-2-溴-NN-双三氟甲基乙烯基胺(比率34:66)和顺式和反式-1,2-二溴-NN-双三氟甲基乙烯基胺(比率64:36)。单独在光解作用下的反式-1,2-二溴-NN-双三氟甲基乙烯基胺会部分异构化,得到顺式-和反式的比例64烯烃:36. 1,2-二溴-的混合物的脱溴化氢NN -bistrifluoromethylvinylamine异构体给出溴NN -bistrifluoromethylethynylamine以良好的收率和本乙炔也由反应形成的NN -双三氟甲基乙炔胺与碱性次溴酸盐。溴-NN-双三氟甲基
