Versuchsvorschrift

In the same apparatus and procedures as EXAMPLE 1, 19.3 g (210 mmol) of toluene and 0.9 g (7.0 mmol) of aluminum chloride were placed and reacted with 10.0 g (70 mmol) of allyldichlorosilane under the dry nitrogen atmosphere for 30 min. After stirring the solution for another an hour, 2.0 g (30 mmol) of sodium chloride was added to reaction mixture, warmed up to 50° C. and stirred for two hours to deactivate the catalyst. Vacuum distillation of the reaction products gave 11.7 g (bp, 73°-76° C./0.5 mmHg) of of 3-(methylphenyl)-1,1-dichloro-1-silabutane in 71% yield.
