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

Interfacial chemistry provides an opportunity to control dynamic materials. By harnessing the dynamiccovalent nature of imine bonds, emulsions are generated in situ, predictably manipulated, and ultimately destroyed along liquid-liquid and emulsion-solid interfacesthrough simple perturbation of the imine equilibria. We report the rapid production of surfactants and double emulsions through spontaneous
