The invention relates to a method for producing alkali metal salts having monofluoro-tricyanoborate anions from alkali metal tetrafluoroborates.

Method for producing salts having monofluoro-tricyanoborate anions

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.

Process for the preparation of perfluoroalkylcyano- or perfluoroalkylcyanofluoroborates

The invention relates to new compounds containing alkyl/alkenyl-cyano-borate or alkyl/alkenyl-cyano-fluoroborate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.

Compounds containing alkyl-cyano-borate or alkyl-cyano-fluoroborate anions

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 4C atoms or phenylcyanofluoroborate anions which are mono- or disubstituted by perfluoroalkyl groups having 1 to 4C 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.

The present invention relates to compounds containing perfluoroalkyl-cyano-alkoxy-borate anions or perfluoroalkyl-cyano-alkoxy-fluoro-borate anions, ((per)fluoro)phenyl-cyano-alkoxy-borate anions or ((per)fluoro)phenyl-cyano-alkoxy-fluoro-borate anions or phenyl-cyano-alkoxy-borate anions which are monosubstituted or disubstituted with perfluoroalkyl groups having 1 to 4 C atoms or phenyl-cyano-alkoxy-fluoro-borate anions which are monosubstituted or disubstituted with perfluoroalkyl groups having 1 to 4 C atoms, the preparation thereof and the use thereof, in particular as part of electrolyte formulations for dye sensitized solar cells.

Compounds containing perfluoroalkyl-cyano-alkoxy-borate anions or perfluoroalkyl-cyano-alkoxy-fluoro-borate anions

The invention relates to new compounds containing alkyl-alkoxy-cyano-borate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.
