Versuchsvorschrift
Five millimoles of 1,1,1,3,5,5,5-heptamethyltrisiloxane, 5 mmol of dimethylphenylvinylsilane, and 5 mmol of dimethylethoxyphenylsilane were mixed. To the mixture were added 5 mmol of water, 5×10-4 mmol of a platinum-vinylsiloxane complex, and 0.1 mmol of hydrochloric acid, followed by stirring at room temperature for 3 hours. Quantitative determination of the reaction product by gas chromatography revealed that 2,2-di-trimethylsiloxy-5-phenyl-5-methyl-2,5-disilahexane was obtained in a yield of 99% as a hydrosilylation addition product and 1,3-diphenyl-1,1,3,3-tetramethyldisiloxane was obtained in a yield of 99% as an alkoxysilane condensation product.
