Fluorine-containing N-arylhydroxylamines have been obtained by the action of hydroxylamine or its N- and O-derivatives on polyfluorinated benzenes and pentafluoropyridine. The influence of fluorine atoms on the reactivity of hydroxylamino group has been investigated. The reaction of N-polyfluoroarylhydroxylamines with aldehydes has been shown not to occur, whereas their reaction with nitrosobenzenes
含氟的N-芳基羟胺是通过羟胺或其N-和O-衍生物对多氟苯和五氟吡啶的作用而获得的。已经研究了氟原子对羟氨基反应性的影响。N-聚氟芳基羟胺与醛的反应已表明不会发生,而它们与亚硝基苯的反应则可生成oxy氧基苯,而与路易斯酸的反应则可生成相应的亚硝基苯,a氧基苯和苯胺。酸对2,3,5,6-四氟苯羟胺的作用导致后者的酸催化重排成4-氨基-2,3,5,6-四氟苯酚。通过用MnO 2氧化获得C,N-二芳基硝酮 在α位具有CH-片段的含氟芳基羟胺。
