Synthesis of fluorinated amides

Abstract

A fluoropolyalkylether is prepared under mild reaction condictions by combining a fluoropolyalkylether substituted with one or more ester end-groups with an amine. Embodiments include combining: (i) a fluoropolyalkylether substituted with one or more ester end-groups having the formula: Rf—(COOR′)q with (ii) an amine having the formula: HNR1R2 and (iii) a solvent comprising a hydrofluorocarbon or a hydrofluoroether together with a lower alcohol at a temperature of from about 15° C. to about 30° C. to form the fluoropolyalkylether amide, where Rf is a perfluoropolyether, R′ is a lower alkyl group, q is 1-4; R1 is H and R2 is a C2-C4 or a C2-C4 substituted with at least one hydroxyl group.
