Procedimiento

Triallyl 3-iodopropyl silane was prepared by the Finkelstein transhalogenation reaction from chloropropyl silane prepared in Example 6. A 250 ml flask equipped with a stir bar and a reflux condenser was charged with 20 grams (90 millimoles) of triallyl (3-chloropropyl) silane (prepared as described in Example 6) and 100 ml of acetone (available commercially as Omnisolve Reagent grade from E. Merck, Gibbstown, N.J.). The silane solution was refluxed under positive nitrogen pressure with 40 grams (270 millimoles) of sodium iodide (available commercially from Aldrich Chemical Co. of Milwaukee, Wis.) for 18 hours. After cooling, the acetone solution was decanted from the insoluble iodide salts and was concentrated on a rotary evaporator to yield triallyl 3-iodopropyl silane, which was used without further purification.
