Versuchsvorschrift

A solution of trimethylchlorosilane (7.82 g, 72.4 mmole) in dry tetrahydrofuran(THF) (40 mL) was added dropwise over a 90 minute period to a solution of (4-vinylphenyl)magnesium chloride, prepared from 4-vinylphenylchloride (10 g, 72.4 mmole) and magnesium (2.43 g, 100 mmole) in dry THF (100 mL). Temperature was maintained at 10° C. during the addition. The reaction mixture was stirred at room temperature over 20 hours under nitrogen atmosphere. The crude product was obtained by direct distillation at 45°-48° C./0.5 mm in 45% yield.
