Page/Page column 4, (2010/08/07)
There are provided simple processes for preparing a fluoroamide and a fluoronitrile which assure higher yield, i.e., a process for preparing a fluoroamide represented by the formula (2): CF2═CF—Rf—CONH2, wherein Rf is a perfluoroalkylene group or perfluorooxyalkylene group having 2 to 20 carbon atoms, by allowing a fluoroester represented by the formula (1): CF2═CF—Rf—COOR, wherein Rf is as defined above; R is an alkyl group having 1 to 6 carbon atoms, to react with ammonia or ammonium hydroxide, and a process for preparing a fluoronitrile represented by the formula (3): CF2═CF—Rf—CN, wherein Rf is as defined above, by allowing the fluoroamide obtained by the above-mentioned preparation process to react with a dehydrating agent (c) in a solvent (b) having an ether bond, an ester bond, a ketone group or a cyano group.

Alkyl perfluoro-ω-fluoroformyl esters are provided which have the formula STR1 wherein R is alkyl of 1-6 carbon atoms, and N IS 0-6 (PREFERABLY 0). Compounds where n is 0 are prepared by contacting SO3 with a compound of the formula Compounds where n is 1-6 are prepared by contacting a compound where n is 0 with hexafluoropropylene oxide. Also provided are polymerizable monomers having the formula STR2 wherein Y is --COOR, --COOH, --COOM or --CN, where M is an alkali metal, ammonium or quaternary ammonium and p is 1-5, prepared from alkyl perfluoro-ω-fluoroformyl esters of this invention.
