Procedure

In the same apparatus and procedures as EXAMPLE 1, 10.0 g (0.046 mole) of 3-phenyl-1,1-dichloro-1-silabutane, 7.2 g (0.07 mole) of styrene, and 20 μl of 1% chloroplatinic acid in isopropanol were placed and reacted for 3 hours under the dry nitrogen atmosphere at 60° C. Vacuum distillation of the reaction products gave 11.0 g (bp, 133°-5° C./0.6 mmHg) of 3,3-dichloro-1,5-diphenyl-3-silahexane.
