Reaction of perfluorocyclopentadiene with N-allyltrifluoroacetamide at 50° gave a Diels–Alder adduct, N-(1,4,5,6,7,7-hexafluorobicyclo[2,2,1]hept-5-en-2-ylmethyl)trifluoroacetamide. The corresponding amine, generated by hydrolysis of the amide, isomerised spontaneously to 1,2,3,7,8,8-hexafluoro-4-azatricyclo[4,2,1,0]nonane, thus indicating that the amide adduct was predominantly, or even exclusively
全氟环戊二烯与N-烯丙基三氟乙酰胺在50°下反应,得到狄尔斯-阿尔德加合物N-(1,4,5,6,7,7-六氟双环[2,2,1]庚-5-烯-2-基甲基)三氟乙酰胺。由酰胺水解产生的相应胺自发异构化为1,2,3,7,8,8-六氟-4-氮杂三环[4,2,1,0]壬烷,因此表明酰胺加合物主要是或什至是排他性的内异构体。
