4-FLUORO-3-FORMYLBENZENEBORONIC ACID - Reference Information
| application | 4-fluoro-3-aldehyde phenylboronic acid can be used as an intermediate in organic synthesis and a pharmaceutical intermediate, mainly used in laboratory research and development processes and chemical and pharmaceutical production processes. |
| preparation | FeCl2 (3.2 mg, 0.025 mmol), aryl boron (0.25 mmol), K2S2O8 (68.3 mg, 0.25 mmol), tetra-n-butyl ammonium bromide (40.7 mg, 0.125 mmol), MeCN (1 mL), H2O (1 mL) and polymethylhydrosiloxane (170 μL), 0.75 mmol) into a 25 mL flask. The reaction mixture was stirred at atmospheric pressure and 80°C for 12 hours. Cool the mixture to room temperature. Dilute the reaction mixture with 10 mL saline and extract with ethyl acetate (3 x 10 mL) . The organic phases are combined and concentrated to obtain a crude product. The residue was purified by silica gel column chromatography (petroleum ether/ethyl acetate) to give (4-fluoro-3-formylphenyl) boric acid. |
