A mixture of 8-bromo-1-octene (1.34 g, 7 mmol) and sodium iodide (5.25 g, 35 mmol) in 2-butanone (15 ml) was stirred under reflux for 1 h. The mixture was concentrated in vacuo to a half of its original volume and hexane and water was added. Organic layer was washed with 5% aqueous sodium thiosulfate, saturated sodium bicarbonate and brine, dried over anhydrous sodium sulfate and concentrated in vacuum. Purification by flash chromatography on silica gel (hexane) gave 8-iodo-1-octene as colorless oil. yield: 1.54 g (92%).
