light brown to brown crystalline solid | [Uses]
2-Bromo-4-fluorophenol was used in preparation of 4,4-difluoro-2-bromo-cyclohexadienone and 6-(aminomethylphenoxy)benzoxaborole analogs. | [Synthesis]
GENERAL METHOD: BiCl3 (30 mol%) was added to a stirred solution of MeCN/H2O (5:0.1 mL; 5:0.1 v/v) containing MOM-protected phenol (1 mmol). The reaction mixture was stirred at 50 °C until the reaction was complete (monitored by TLC). Upon completion of the reaction, the mixture was filtered using CH2Cl2 (10 mL) over a pad of diatomaceous earth. The filtrate was dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent hexane/EtOAc mixture) to afford the target product 2-bromo-4-fluorophenol in 76-95% yield. All phenolic products were analyzed by IR and NMR spectroscopy and verified by comparison with real samples. | [References]
