実験手順
To a stirred solution of 2-(1,1,2,2-tetrafluoroethoxy)toluene (2.5 g, 12.2 mmol) in CCl4 (75 mL) was added NBS (2.1 g, 13 mmol) and AIBN (0.65 g, 3 mmol). The mixture was refluxed for 6 h. The solvent was removed under reduced pressure and the residue was partitioned between EtOAc (75 mL) and water (50 mL). The organic phase was separated, dried (MgSO4), filtered, and the solvent was removed under reduced pressure. The residue was purified by pressurized silica gel column chromatography using hexanes as eluant to give 2-(1,1,2,2-tetrafluoroethoxy)benzyl bromide as a colorless liquid (TLC Rf =0.7 (hexanes)).
