Reaction Conditions

Reaction Steps

Into a 3 liter round-bottom flask fitted with a reflux condenser, addition funnel and magnetic stir bar, was charged 4-methylstyrene (900 g, 7.6 mols) and Bis(triphenylphosphine)palladium (II) dichloride (1.8 g, 0.2% wt). The reaction mixture was heated to 70° C. and then trichlorosilane (1031 g, 7.6 mols) was added dropwise to the reaction mixture. During the addition, the reaction mixture was maintained between 80 to 100° C. After the addition was finished, the reaction mixture was kept at 70° C. for additional two hours. After distillation, pure (1-p-tolyl-ethyl)trichlorosilane (1400 g, 5.53 mols) was obtained (collected at 75° C./1 mmHg). The product structure was characterized by GC-MS and 13C NMR (δ˜14 ppm, CDCl3, Cl3Si—CH (CH3)-Ph; δ˜35 ppm, CDCl3, Cl3Si—CH(CH3)-Ph).
