Versuchsvorschrift

An ethereal solution of magnesium iodide was prepared by adding 4.85 g (19 mmol) of iodine to 0.46 g (19 mmol) of magnesium in suspension in 40 ml of dry ether. 28 ml of this solution was added to a solution containing the crude 3-(trimethylsilyl)-1-propanol, methanesulfonate in 10 ml of ether. The reaction mixture was stirred for 3 hours at room temperature and then partitioned between ether and water, the organic phase was separated and further washed with aqueous sodium thiosulfate. After evaporation of the solvent, 1.6 g of (3-iodopropyl)trimethysilane was obtained as a colorless liquid.
