The invention relates to a method for producing salts having perfluoroalkyl tricyanoborate or perfluoroalkyl cyanofluoroborate anions, ((per)fluoro)phenyl tricyanoborate or ((per)fluoro)phenyl cyanofluoroborate anions, phenyl tricyanoborate anions monosubstituted or disubstituted by perfluoroalkyl groups having 1 to 4 C atoms or phenyl cyanofluoroborate anions monosubstituted or disubstituted by perfluoroalkyl groups having 1 to 4 C atoms by reacting alkali metal trifluoroperfluoraklyl borate and trialkylsilyl cyanide and a subsequent salt conversion reaction or by directly reacting an organic trifluoroperfluoroalkyl borate and trialkylsilyl cyanide. |
