Participants

Reaction Steps

Compound 4-(methyldiisopropyloxysilyl)styrene (8.23 g, 31 mmol) was dissolved in dry methanol (10 ml,). 1% molar of p-toluene sulfonic acid (17 mg) was added all at once. The yellow suspension was stirred for 4 hours. The organic solvent was pumped off and the corresponding crude oil was distilled under vacuum (B.p. 70-80° C., 5.10−2 mbar) to afford 4-(methyldimethoxysilyl)styrene as a yellow oil (4 g, 20 mmol) in 65% yield. 1H NMR (CDCl3, δ, ppm) 7.64 (2H, d); 7.49 (2H, d); 6.77 (1H, dd), 5.84 (1H, d), 5.33 (1H, d), 3.60 (6H, s); 0.39 (3H, s).
