1245906-64-2 - Reference Information
| Introduction | (5-bromo-2-fluoropyridine-3-yl) potassium trifluoroborate is an aryl potassium trifluoroborate derivative. Potassium aryl trifluoroborate not only has high stability and good crystallinity, but also has the closest reaction performance to the corresponding aryl boronic acid. It is the most promising aryl boronic acid derivative in industrial production and application. |
| prepare | 5-bromo -2-fluoropyridine -3-boric acid (0.41 mol), potassium difluoride (0.82 mol), stir at 500rpm for 10 minutes at a high speed to obtain a uniformly mixed material, which is continuously added through the feed port of the twin-screw extruder, and the extrusion time is set to 5 minutes, the extruded material is directly received in a receiver containing the same weight of water as the solid material, stirred and dispersed to obtain a slurry, filtered, the filtrate is returned to the receiver, and the filter cake is washed with hot air to dry the product (5-bromo-2-fluoropyridine-3-based) potassium trifluoroborate. |
