3-(2-Allyloxy-ethoxy)-propene (20 g, 0.141 mol) and 40 mg of hydrogen hexachloroplatinate (IV) hydrate were added to a 250-mL air-free flask with a condenser. Trichlorosilane (40 mL, 0.396 mol) was added dropwise to the stirred solution which was subsequently heated in an oil bath of 80° C. The reaction mixture was heated at reflux for 4 hours and then distilled in vacuum. The fraction containing di(3-trichlorosilyl)propyl ethylene ether (39 g, 0.0944 mol) at 90° C. and 20 mtorr was collected with a yield of 70% based on 3-(2-allyloxy-ethoxy)-propene. 1H NMR (400 Mz, CDCl3): δ 1.5 (t, 2H), 1.8 (m, 2H), 3.4 (t, 2H), 3.6 (t, 2H). 29Si NMR (79.6 Mz, CDCl3): 13.4 (s).
