| titleOfInvention | Method for purifying tetrakis(fluoroaryl) borate/magnesium halide, tetrakis(fluoroaryl) borate/ether complex and process for preparing the same, and process for preparing tetrakis(fluoroaryl) borate derivative |
| abstract | A method for purifying Ar4BMgX which comprises treating a tetrakis(fluoroaryl) borate/magnesium halide (Ar4BMgX) with (1) an alkaline (earth) metal salt of carboxylic acid, (2) an acid, (3) an acid and then an alkaline (earth) metal hydroxide, or (4) an acid and then an alkaline (earth) metal salt of carboxylic acid; and a process for preparing a tetrakis(fluoroaryl) borate derivative (Ar4BZ) which comprises reacting the treated Ar4BMgX with a compound capable of generating monovalent cationic species. The above purification method permits separation and removal of impurities contained in Ar4BMgX in an efficient and simple manner. The invention also provides a tetrakis(fluoroaryl) borate/ether complex, a process for preparing the same, and a process for preparing a tetrakis(fluoroaryl) borate derivative (Ar4BZ) by using the ether complex and the compound capable of generating monovalent cationic species as starting compounds. The ether complex can be easily purified to a high purity and hence is suitable as an intermediate for the preparation of various tetrakis(fluoroaryl) borate derivatives. |
