Definitions
- the present invention relates to new processes for the preparation of bis (trifluoromethyl) imido salts of the general formula (I):
- Cesium bis (trifluoromethyl) imide, [Cs] + [N (CF 3 ) 2 ] " is another option for the synthesis of bis (trifluoromethyl) amino compounds.
- This salt is obtained by simply introducing perfluoro (2-azapropene) into prepared a solution of cesium fluoride in dry acetonitrile (AF Gontar, EG Bykovskaja and IL Knunyants, IZV. Akad. Nauk SSSR, Otd. Khim, Nauk (1975), pp. 2279-2282).
- N (CF 3 ) 2 anions are readily accessible through the reaction of some metal fluorides with N, N-bis (trifluoromethyl) perfluoroalkanesulfonamides or acylamides [,, N (CF 3 ) 2 anion preparation and its use ", EP 99 101 982]. With this method it is possible to generate Na, K, Rb, Cs, Ag, Cu (ll) and Hg (ll) salts with N (CF 3 ) 2 anions.
- N-bis (trifluoromethyl) perfluoroalkane sulfonamides or acylamides with other metal fluorides progress only very slowly, owing to the poor solubility of these fluids in organic solvents.
- the object of the present invention was therefore to provide an improved process for the preparation of bis (trifluoromethyl) imido salts.
- the object of the invention is achieved by a process for the preparation of bis (trifluoromethyl) imido salts of the general formula (I),
- M a + denotes a cation of the general formula (III) are also particularly preferred,
- Kt N, P, As, Sb, S, Se,
- A N, P, P (O), O, S, S (O), S0 2 , As, As (O), Sb, Sb (O),
- R 1 , R 2 , R 3 and R 4 the same or different
- n 1-18,
- A can be enclosed in different positions in R 1 , R 2 , R 3 and / or R 4 ,
- Kt can be enclosed in a cyclic or heterocyclic ring
- the groups bound to Kt may be the same or different.
- New bis (trifluoromethyl) imido salts such as cadmium, zinc or copper (I) -N (CF 3 ) 2 salts, which are difficult to access, can also be prepared using the processes according to the invention.
- the new salts therefore constitute a further subject of the present invention.
- the salts produced according to the invention can be used alone or in mixtures with other salts as conductive salts or additives in electrolytes.
- the electrolytes also contain solvents or solvent mixtures.
- electrolytes are used in electrochemical cells (such as primary and secondary batteries). They are preferably used in capacitors and supercapacitors.
- the starting materials bis (trifluoromethyl) imido rubidium and the trifluoromethanesulfonate salts are both good in a number of organic ones Solvents soluble. Metal triflates are also commercially available from a number of companies.
- the conversion to a bis (trifluoromethyl) imido salt of the general formula (I) takes place preferably at a temperature of -60 to +60 ° C, particularly preferably from -50 to +50 ° C, very particularly preferably at -45 to +30 ° C.
- Preferred solvents for the conversion to a bis (trifluoromethyl) imido salt of the general formula (I) are organic solvents, particularly preferably polar organic solvents.
- Very particularly preferred solvents for the conversion to a bis (trifluoromethyl) imido salt of the general formula (I) are the solvents acetonitrile, benzonitrile, dimethoxyethane and / or propionitrile or a mixture of acetonitrile, benzonitrile, dimethoxyethane and / or propionitrile.
- Preferred methods according to the invention contain ⁇ 0.1% by weight of water, preferably ⁇ 0.01% by weight of water, particularly preferably ⁇ 0.005% by weight of water.
- the trifluoromethanesulfonate salt of the general formula (II) or the Bis (trifluoromethyl) imido rubidium in a molar excess ⁇ 3% or particularly preferably used in equimolar amounts.
- the rubidium triflate formed by the process according to the invention has a limited solubility in organic solvents and can be separated from the reaction mixture as a solid at low temperatures.
- the processes according to the invention are therefore preferred in which the bis (trifluoromethyl) imido salt of the general formula (I) is obtained by filtration at a temperature of -90 to +30 ° C., particularly preferably at -70 to +20 ° C. and after removal of the solvent is cleaned.
- the solvent was filtered off with suction and a small amount of CD 3 CN (approx. 30%) was added and the mixture was characterized by 19 F NMR spectroscopy at -45 ° C.
- the signal at -44.83 ppm is assigned to the Zn [N (CF 3 ) 2 ] 2 , which is coordinated with the solvent.
- the solvent was filtered off with suction and a small amount of CD 3 CN (approx. 30% by volume) was added and the mixture was characterized by 19 F NMR spectroscopy at -40 ° C.
- the signal at -42.53 ppm is the Cd [N (CF 3 ) 2 ] 2 assign that is coordinated with the solvent.
- the signal of the N (CF 3 ) 2 group in the 19 F NMR spectrum shifts to - 45.39 ppm.
- the salt Cd [N (CF 3 ) 2 ] 2 nC 2 H 5 CN has only a low stability as an analyte at room temperature.
- Lithium reference electrode was recorded several cyclovoltammograms in a row. For this purpose, starting from the resting potential, the potential was first increased at a feed rate of 20 mV / s to 6 V against Li / Li + and then moved back to the resting potential. A solution of [N (C 2 H 5 ) 4 ] [N (CF 3 ) 2 ] in propylene carbonate was used as the electrolyte.
