N-perfluoroaryl imines by m-chloroperoxybenzoic acid (MCPBA) in sulfolane leads to the formation of the corresponding oxaziridines in 60%–90% yield. At elevated temperature the N-aryloxaziridines readily rearrange into the respective N-arylamides of chlorodifluoro- and trifluoro-acetic acid.
通过六氟丙酮,氯五氟丙酮和1,3-二氯四氟丙酮的亚胺与五氟吡啶或全氟甲苯的反应,制备了未知的多氟酮全氟芳基亚胺,产率为60%-70%。这些氧化Ñ -perfluoroaryl亚胺由米在环丁砜通向对应氧氮环丙烷的形成氯过氧苯甲酸(MCPBA)在60%-90%的产率。在升高的温度下,N-芳基氧氮丙啶易于重新排列成氯代二氟乙酸和三氟乙酸的相应的N-芳基酰胺。
