PROCEDURE
实验过程
Into a 50-mL round-bottom flask was placed dichloromethane (20 mL) and 2-(2-ethoxyphenyl)ethan-1-ol (1.33 g, 8.00 mmol, 1.00 equiv). The solution was cooled to 0° C. in a water/ice bath. Then PPh3 (2.72 g, 10.37 mmol, 1.30 equiv), imidazole (707 mg, 10.40 mmol, 1.30 equiv) and I2 (2.44 g, 9.61 mmol, 1.20 equiv) were added. The resulting solution was stirred at room temperature overnight. The reaction was then quenched by the addition of 50 mL of NaHSO3 (aq.). The organic layer was separated and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (0:100). Purification afforded 1.34 g (61%) of 1-ethoxy-2-(2-iodoethyl)benzene as a colorless oil.
