Procedure

In the same apparatus and procedures as EXAMPLE 1, 8.5 g (0.034 mole of 3-(2,5-dimethylphenyl)-1,1-dichloro-1-silabutane, 8.7 g (0.10 mole) of 1-hexene, and 120 μl of 1% chloroplatinic acid in isopropanol were placed and refluxed under the dry nitrogen atmosphere for 3 hours. Vacuum distillation of the reaction products gave 7.4 g (bp, 130°-3° C./0.6 mmHg) of 4,4-dichloro-2-(2,5-dimethylphenyl)-4-siladecane.
