| titleOfInvention | Method of producing Ph3 C[B(C6 F5)4 ] |
| abstract | A method for producing Ph3C[B(C6F5)4] in an improved yield by reacting LiB(C6F5)4, which has not been isolated between production and use, with Ph3CCl preferably in a molar ratio of LiB(C6F5)4 to Ph3CCl of 1:(1+/-0.05), and preferably in the presence of a hydrocarbon solvent such as an aliphatic hydrocarbon containing from 5 to 8 carbon atoms, to give a Ph3C[B(C6F5)4] product; optionally evaporating the hydrocarbon solvent; extracting the resulting Ph3C[B(C6F5)4] product; separating insoluble LiCl, and isolating the product. The product may be isolated, for example, by freeing it of solvent, thereafter dissolving the product in toluene to form a toluene solution, introducing the toluene solution into a hydrocarbon solvent to form crystals of the product, and recovering the crystals. In the method, the LiB(C6F5)4 is used in the form of a hydrocarbon preparation, preferably a reaction mixture obtained in the synthesis of LiB(C6F5) 4, the concentration of may be adjusted by concentrating or diluting as needed to obtain a preferred LiB(C6F5)4 concentration of from 20 to 300 grams/liter. |
