dimers were subjected to liquid-phase photofluorination (LPPF). The corresponding perfluorotertiary amines, which were difficult to synthesize by the conventional fluorination methods such as electrochemical fluorination and indirect fluorination using high-valency metal fluorides, were obtained in good yields. Prepared by this method were F-(N,N-dimethyl-2- methylpentyl) amine 3, F-(N,N-diethyl-2-methylpentyl)
对衍生自六氟丙烯二聚体的叔胺进行液相光氟化(LPPF)。以良好的收率获得了相应的全氟叔胺,它们难以通过常规的氟化方法如电化学氟化和使用高价金属氟化物的间接氟化来合成。用这种方法制备的是F-(N,N-二甲基-2-甲基戊基)胺3,F-(N,N-二乙基-2-甲基戊基)胺4,F -3-(1-吡咯烷基)-2-甲基戊烷11,F-(N,N-二甲基-1,1-二甲基丁基)胺13。关于F -2-甲基-2-戊烯(D-II)与仲胺反应的区域选择性的讨论也与制备区域选择性加合物3-(1-吡咯烷基)-F -2的必要性有关。-甲基-2-戊烯,用于合成11。
