The present invention relates to compounds containing hydrido-tricyano-borate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.

Compounds containing hydrido-tricyano-borate anions

The present invention relates to intermediate compounds for the preparation of hydrido-tricyano-borate anions, their preparation and their uses.

The invention relates to a process for the preparation of alkali-metal salts with dihydridodicyanoborate anions by reaction of alkali-metal tetrahydridoborates or trihydridocyanoborates with trialkylsilyl cyanide and further reaction thereof in metathesis reactions.

Process for preparing dihydridodicyanoborate salts

The present invention relates to dyes of the general formula CATY(I), where Yis an anion selected from the group of the cyanoborates, fluoroalkylphosphates, fluoroalkylborates or imidates and CATis a cation selected from the group of the azine, xanthene, polymethine, styryl, azo, tetrazolium, pyrylium, benzopyrylium, thiopyrylium, benzothiopyrylium, thiazine, oxazine, triarylmethane, diarylmethane, methine, acridine, quinoline, isoquinoline or quaternary azafluorenone dyes, for coloring plastics and plastic fibers, for the preparation of flexographic printing inks, as ball-point pen pastes, as stamp ink, for coloring leather and paper, for use in data acquisition systems, reprography, in ink microfilters, in photogalvanics, laser technology and the photo industry.

Cyanoborate, fluoroalkylphosphate, fluoroalkylborate or imide dyes

The invention relates to boron-containing acids of the general formula (I) [B(R)(CN)F]H(I), where x=0, 1, 2, 3 or 4, y=0, 1, 2 or 3 x+y&#x2266;4, and in which the ligands Rmay be identical or different and Rstands for a perfluorinated or partially fluorinated C-alkyl group and where the CN group is bonded to the B atom via the C atom, and complexes thereof with a solvent, to salts comprising a cation and the anion of a selection of the acids according to the invention, and to processes for the preparation of the salts.

Strong boron-containing acids, the preparation and use thereof

The invention relates to salts having alkoxytris(fluoroalkyl)borate anions which on the one hand are used for the synthesis of ionic liquids, but on the other hand can be employed per se as ionic liquid, and to processes for the preparation thereof.

Salts having alkoxytris(fluoroalkyl)borate anions

The present invention relates to dyes of the general formula CATY(I), where Yis an anion selected from the group of the cyanoborates, fluoroalkylphosphates, fluoroalkylborates or imidates and CATis a cation selected from the group of the azine, xanthene, polymethine, styryl, azo, tetrazolium, pyrylium, benzopyrylium, thiopyrylium, benzothiopyrylium, thiazine, oxazine, triarylmethane, diarylmethane, methine, acridine, quinoline, isoquinoline or quaternary azafluorenone dyes, for colouring plastics and plastic fibres, for the preparation of flexographic printing inks, as ball-point pen pastes, as stamp ink, for colouring leather and paper, for use in data acquisition systems, reprography, in ink microfilters, in photogalvanics, laser technology and the photo industry.

A process for the preparation of alkali metal cyanoborates, the further conversion thereof into salts comprising cyanoborate anions and organic cations, these salts, and the use thereof as ionic liquids are described.

Salts comprising cyanoborate anions

The present invention relates to tetrakisfluoroalkylborate salts, methods of producing same, and their use in electrolytes, batteries, capacitors, supercapacitors, and galvanic cells.
