Benzenepropanol → (3-Fluoropropyl)benzene

Participants

Reaction Steps

3-Phenyl-1-propanol (1 mL) and (diethylamino)sulfur trifluoride (1.2 mL) were dissolved in dichloromethane (10 mL). The reaction solution was stirred at rt for 3 d. The reaction mixture was passed through a short silica gel column and washed with dichloromethane. The collected solution was evaporated to give 1-fluoro-3-phenylpropane as light yellow oil. 1H NMR (DMSO-d6): δ 1.84-2.02 (m, 2H), 2.65 (t, J=7.5 Hz, 2H), 4.34 (t, J=5.7 Hz, 1H), 4.50 (t, J=5.7 Hz, 1H), 7.20 (m, 5H); 19F NMR (282 MHz, DMSO-d6): δ−79.22.
