A series of perfluoroalkylenamines of formula RFCF2CHCHNR2 has been obtained by the addition of secondary amines to perfluoroalkylethynes. Only the E isomer is formed. The dominant feature of their chemistry is the lability of the allylic C-F bonds, which is responsible for their instability and for the fact that acid hydrolysis yields mainly the enaminoketones RFCOCHCHNR2, a reaction which provides
通过将仲胺加到全氟烷基乙炔中,可以得到一系列式为R F CF 2 CH = CHNR 2的全氟亚烷基胺。仅形成E异构体。它们的化学性质的主要特征是烯丙基CF键的不稳定性,这是负责它们的不稳定性和一个事实,即酸水解的产率主要是enaminoketonesř ˚F COCHCHNR 2,其提供了一种通用路由到此后一类的反应化合物。另一方面,未观察到烷基化,酰化或溴化。全氟亚烷基氨基酮中CN键周围的旋转受到强烈阻碍(ΔG≠⋍17–18 kcal。mole -1)。报道并讨论了这两个系列化合物的光谱特征。
