The invention relates to a process for the preparation of salts having perfluoroalkyltricyano- or perfluoroalkylcyanofluoroborate anions, ((per)fluoro)phenyltricyano- or ((per)fluoro)phenylcyanofluoroborate anions, phenyltricyanoborate anions which are mono- or disubstituted by perfluoroalkyl groups having 1 to 4 C atoms or phenylcyanofluoroborate anions which are mono- or disubstituted by perfluoroalkyl groups having 1 to 4 C atoms, by reaction of alkali metal trifluoroperfluoroalkylborate with trialkylsilyl cyanide and a subsequent salt-exchange reaction or by direct reaction of an organic trifluoroperfluoroalkyl borate with trialkylsilyl cyanide.
