Reaction Conditions:
at 100;Inert atmosphere;
Steps:
2 Example 2
Under nitrogen protection, tetrakis (tetrahydropyrrole) boron (0.1) was added to a three-necked flask equipped with a dropping and refluxing unitMole) and 50-60 times deionized water, and the temperature was raised to 100 ° C. After refluxing for 1.5 hours, the mixture was replaced by an atmospheric distillation unit,The reaction process to generate tetrahydropyrrole distillation, no longer with tetrahydropyrrole distilled, the reaction solution is cooled to room temperature, at this time a solid precipitation,Filtered and dried to give 8.5 g of whitesolidTetrahydroxy boron, HNMR purity of more than 98%, consistent with the literature.Add 45 ml of methanol, stir at room temperature until completely dissolved (about 10-15 minutes), then add KHF2 aqueous solution (0.38 mol), stirring at room temperature for 1 hour, the system after standing and layered, carefully separated from the lower, Distilled to dry. After addition of acetone, the mixture was filtered to give 15.8 g of potassium boron trifluoride as a white solid, the total yield was 74%
