20100022803 | Method for Producing Tris(Perfluoroalkanesulfonyl)Methide Acid Salt - There is provided a method for producing a tris(perfluoroalkanesulfonyl)methide acid salt represented by formula [1], including the steps of (a) reacting a methylmagnesium halide represented by formula [2] with a perfluoroalkanesulfonyl fluoride represented by formula [3], thereby obtaining a reaction mixture; and (b) directly reacting the obtained reaction mixture with at least one selected from the group consisting of alkali metal halides, quaternary ammonium salts, and quaternary phosphonium salts. By this method, it is possible to easily produce the target methide acid salt with high yield. | 01-28-2010 |
20110065857 | Fluorine-Containing Polymer and Anti-Static Agent Wherein Same is Used - There is provided a fluorine-containing polymer having a repeating unit of the general formula (2) and produced by homopolymerization or copolymerization with an other polymerizable double bond-containing monomer. | 03-17-2011 |
20110070544 | Novel Salt Having Fluorine-Containing Carbanion Structure, Derivative Thereof, Photoacid Generator, Resist Material Using the Photoacid Generator, and Pattern Forming Method - There is provided an acid having a fluorine-containing carbanion structure or a salt having a fluorine-containing carbanion structure, which is represented by the following general formula (1). | 03-24-2011 |
