| Physical and Chemical Properties | Trans (pentafluorobenzene) boron is a strong Lewis acid that is more acidic than BF3 and weaker than bcl3. Boron (pentafluorobenzene) is a powdery solid that is stable even at a high temperature of 270 ° C. And is stable against water and oxygen. However, both BF3 and BCl3 are gases, which brings great inconvenience to the use. Complexes with weak Lewis bases such as diethyl ether and acetonitrile are easier to use, but the Lewis acidity is reduced. Trans (pentafluorobenzenes) boron and water can form stable complexes without decomposition. |
| Use | Commonly used reagents, used to prepare d0 aromatics and other organometallic complexes, and also used in polymerization catalysts. |

Tris(pentafluorophenyl)boron - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| introduction | trans (pentafluorophenyl) boron is also called tris (pentafluorophenyl)borane. compared with traditional Lewis acid, it has the advantages of stable chemical properties, strong acidity and convenient use, and is called non-traditional Lewis acid. The application field of trans (pentafluorobenzene) boron has developed from the initial olefin polymerization co-catalyst to other fields of organic chemistry and polymer chemistry. The reaction catalyzed by tris (pentafluorophenyl) borane is very different from the reaction catalyzed by traditional Lewis acid in the reaction mechanism and reaction results. |
| application | trans (pentafluorobenzene) boron is a commonly used reagent, used to prepare d0 aromatics and other organometallic complexes, and also used for polymerization catalyst. |
| preparation | three-mouth bottle (250mL) after adding pentafluorobromobenzene (0.09mol,22.2g), add 2-methyl tetrahydrofur nan (100mL). N-BuLi(2.5M,0.09mol,36mL) was added dropwise at 25 ℃, and after the reaction was 6.0h , trimethyl borate (0.03mol,3.1g) was added dropwise at 25 ℃ for 10min. After reaction at 25 ℃ for 16h, GC monitored the reaction. Pour the reaction liquid into water, extract it twice with 2-methyltetrahydrofuran, merge the organic layer, wash it twice with water, wash it once with saturated salt water, dry the organic layer with sodium sulfate, evaporate to 2-methyltetrahydrofuran under reduced pressure, and recover 2-methyltetrahydrofuran to obtain a crude product, and recrystallize with n-hexane to obtain trans (pentafluorobenzene) boron (0.0049mol,2.48g), the yield is 16.2%. |
| use | used to prepare organometallic complexes and polymerization catalysts commonly used reagents, used to prepare d0 aromatics and other organometallic complexes, and also used for polymerization catalysts. |
