Procedure
To a solution of 4-acetoxybenzyl alcohol (0.332 g, 2 mmol), and cesium iodide (0.571 g, 2.2 mmol) in anhyd. acetonitrile (10 mL) under nitrogen, boron trifluoride etherate (0.28 mL, 2.2 mmol) in acetonitrile (5 mL) was introduced. After stirring overnight, the reaction mixture was poured into ice-cold water (20 mL) and the solid separated was filtered, washed with water and later with hexanes. The product was dried under high vacuum. Yield, 0.39 g, 71%; TLC, hexanes:EtOAC (4:1). 1H NMR (CDCl3): δ 2.3 (s, 3H), 4.35 (s, 2H), 7.05 (d, 2H), 7.5 (d, 2H).
