Dichlorodimethylsilane → Vinylphenyldimethylchlorosilane

참여 물질

반응 단계

(4-Vinylphenyl)magnesium chloride was synthesized by the gradual dropwise addition of 50 parts of p-chlorostyrene to a mixture of 15 parts magnesium turnings and 100 parts tetrahydrofuran. This was gradually added dropwise over 2 hours to 50 parts of dimethyldichlorosilane dissolved in 100 parts tetrahydrofuran, after which the reaction was heated for an additional 1 hour under reflux. The reaction solution was cooled and then filtered and the solvent was distilled off. Distillation of the residual liquid at 1 mmHg yielded 50 parts of 4 vinylphenyldimethylchlorosilane. The product was identified by mass spectrometric analysis and 1H-, 13C-, and 29Si-NMR spectroscopy.
