Procedure

Allylmagnesium chloride was synthesized by the gradual dropwise addition of 50 parts of allyl chloride to a mixture of 15 parts of magnesium turnings and 100 parts of tetrahydrofuran. This was gradually added dropwise over a period of 2 hours to 18 parts of methyldichlorosilane dissolved in 100 parts of tetrahydrofuran, and the reaction was then heated for an additional 1 hour under reflux. After cooling the reaction, the solution was filtered, the solvent was distilled off, and the residual liquid was distilled at 1 mmHg. 15 parts of diallylmethylsilane was obtained. The silicon-bonded hydrogen in this compound was replaced by chlorine by a standard method. Distillation then yielded the target compound.
