Versuchsvorschrift

90 g of 3-chloropropyltris(trimethylsiloxy)silane (27) (Chem. Abstracts No. 18077-31-1) and 105.22 g of sodium iodide are added to 250 ml of acetone and stirred for 24 hours at reflux. The acetone is evaporated and the residue taken up in methylene chloride. The organic phase is washed with water, dried and evaporated. 89 g of the desired 3-iodopropyl-tris(trimethylsiloxy)silane (28) are obtained; 1H-NMR (ppm, CDCl3): 3.12 2H t, 1.75 2H txt, 0.43 2H t, 0 27H s.
