Versuchsvorschrift

To a solution of 4-(trifluorovinyloxy)benzaldehyde (about 35 mmol) in benzene/ethanol (75/75 mL) at room temperature was added sodium borohydride (1.8 g, 1.3 eq). The resulting mixture was stirred at room temperature for 3 h. Under reduced pressure, all the solvent was evaporated. The residue was extracted by CH2Cl2 for 1 h and dried over sodium sulfate. The product was purified by chromatography using CH2Cl2 as the eluent to afford 4-(trifluorovinyloxy)benzyl alcohol as colorless oil (5.0 g, yield 68%). 1H NMR (CDCl3): δ 7.36 (d, J=8.8 Hz, 2H), 7.09 (d, J=8.8 Hz, 2H), 4.67 (s, 2H), 2.03 (s, 1H).
