実験手順

148 g (1.0 mol) of 2-allylanisole are mixed with 8 mg of hexachloroplatinic acid under a nitrogen atmosphere and heated to 70° C. 114 g (1.2 mol) of dimethylchlorosilane are metered into the mixture over the course of two hours and the mixture is stirred at 70° C. for a further four hours. Excess dimethylchlorosilane is then removed in vacuo and 2-propenylanisole which is formed by isomerization is separated off using a short Vigreux column. 204 g of 3-(2-anisyl)propyldimethylchlorosilane are obtained as a clear liquid having an acid number of 227.
