METHOD FOR PRODUCING FLUOROAMIDE AND METHOD FOR PRODUCING FLUORONITRILE

摘要

Disclosed is a method for producing a fluoroamide represented by the following formula (2): CF2=CF-Rf-CONH2 (wherein Rf is as defined below), wherein a fluoroester represented by the following formula (1): CF2=CF-Rf-COOR (wherein Rf represents a perfluoroalkylene group or perfluorooxyalkylene group having 2-20 carbon atoms, and R represents an alkyl group having 1-6 carbon atoms) is reacted with ammonia or ammonium hydroxide. Also disclosed is a method for producing a fluoronitrile represented by the following formula (3): CF2=CF-Rf-CN (wherein Rf is as defined above), wherein a fluoroamide obtained by the above-described method is reacted with a dehydrating agent (c). This method for producing a fluoronitrile is characterized in that the reaction is carried out in a solvent (b) having an ether bond, an ester bond, a ketone group or a cyano group. The methods enable to produce a fluoroamide or a fluoronitrile with high yield by a simple process.
