Versuchsvorschrift

In the same apparatus and procedures as EXAMPLE 1, 37.5 g (0.153 mole) of 3-(ethylphenyl)-1,1-dichloro-1-silabutane and 100 μl of 1% chloroplatinic acid solution in isopropanol were placed and then 5 g (0.061 mole) of 1,5-hexadiene was added dropwise for 5 min. The solution was reacted for 14 hours at reflux under the dry nitrogen atmosphere. Vacuum distillation gave 24.6 g (190°-192° C./0.03 mmHg) of bis[{2-(ethylphenyl)propyl}dichlorosilyl]hexane in 69.8% yield.
