Reaktionsschritte

Hexachloroplatinic acid hexahydrate (0.02 g, 0.039 mmole) was dissolved in a minimum of 2-propanol. This solution was dissolved in 75 ml toluene under argon. 2-propanol and water were removed by azeotropically distilling 25 ml of the toluene. The resulting solution was stirred and 6.17 g (0.046 mole) of 4-bromo-1-butene was added at 40° C. 4.32 g (0.046 mole) of dimethylchlorosilane was slowly added and the solution was heated to 60° C. and allowed to react for four hours. The mixture was distilled to remove the toluene. Further vacuum distillation yielded 8.0 g of product with a b.p. of 92°-95° C. at 5 mm Hg pressure. 'H NMR confirmed the structure.
