実験手順

At −78° C., pentafluoroiodoethane (2.09 g, 8.51 mmol)) was condensed into a pressure bottle. Toluene (5 mL), 4-ethenylbenzenemethanol acetate (1 g, 5.67 mmol), and tributyltin hydride (1.53 mL, 5.67 mmol) were added. The pressure bottle was sealed and irradiated for 30 hours using a 75 W lamp. The solvent was removed in vacuo. Flash chromatography of the residue gave 525 mg of 4-(3,3,4,4,4-pentafluorobutyl)benzenemethanol acetate; 1H NMR (300 MHz, CDCl3) δ 7.32 (d, 2H), 7.21 (d, 2H), 5.09 (s, 2H), 2.91 (m, 2H), 2.32 (m, 2H), 2.10 (s, 3H) ppm.
