Procedure

A 500 ml Schlenk flask equipped with a stir-bar, a reflux condenser and a rubber septum was charged under nitrogen with 94.6 g of HSiMe2Cl and 5 drops of a 0.1 M solution of the platinum complex Pt(0) 2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane complex (a product sold by Aldrich Chemical Co) at room temperature. To this solution 131 g of Me3SiO—CH2—CH═CH2 was added during 30 minutes. After the addition the reaction mixture was gradually heated at 40° C. and mantained at this temperature under stirring for 2 hours, and finally heated at 60° C. for another 5 hours. The desired product can be isolated by distillation under vacuum (25 mbar) at 84° C. Yield 80%. 1H NMR (CDCl3): 0.125 (s, 9H, SiMe3), 0.413 (s, 6H, SiMe2), 0.798–0.890 (m, 2H, CH2), 1.595–1.720 (m, 2H, CH2), 3.585 (t, 2H, CH2).
