Procedure

In the same apparatus and procedure as EXAMPLE 1, 6.2 g (0.027 mole) of 3-(2,5-dimethylphenyl)-1,1-dichloro-1-silabutane, 5.4 g (0.05 mole) of styrene, and 90 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, 139°-141° C./0.6 mmHg) of 3,3-dichloro-5-(2,5-dimethylphenyl)-1-phenyl-3-silahexane.
