| titleOfInvention | The preparation method of tetrakis (pentafluorophenyl) borate |
| abstract | The invention disclosed in the invention belongs to the technical field of catalytic olefin polymerization, in particular to a preparation method of tetrakis (pentafluorophenyl) borate. , Pentafluorobromobenzene, boron trifluoride-THF, toluene are added in the reactor, and the Grignard initiator is one or more of methyl iodide, ethyl bromide, 2-dibromoethane, and its reaction temperature and Time, after processing, tris (pentafluorophenyl) borane Grignard reagent is obtained, and then tris (pentafluorophenyl) borane Grignard reagent is subjected to secondary treatment, and layering treatment is carried out after the secondary treatment is completed. After layer treatment, final treatment is carried out to obtain the finished product. In the present invention, the target product is directly prepared by reacting the pentafluorobromobenzyl Grignard reagent with polyhalogenated boron or polyhalogenated borate without catalyst, which has better atom economy and does not require The use of special equipment and a specific production environment reduces labor costs and production costs. |
