Nine perfluoroacylfluorides underwent halogen exchange when treated with anhydrous lithium halides to give acyl chlorides, bromides and iodides in high yields. The temperature dependence of this reaction is described. In the reaction with perfluorodiacyl fluoride, the diacyl halides possessing different acyl halide-groups were also produced. Of the alkaline metal salts used halogen exchange was successful

amines CF2CF2OCF2CF2NCFXCF2X (XCl, Br, OSO2F) and CF2CF2OCF2CF2NCF2Br have been reacted with ClOSO2F to give a number of interesting fluorosulfate- containing products. The reactivity of bromine (chlorine) α and β to the nitrogen in these amines is compared. The structure of the products has been confirmed by 19F NMR, infrared and mass spectral studies, and by elemental analyses.
