Reaction Conditions

Reaction Steps

Into a 2-liter round-bottom flask fitted with a reflux condenser, addition funnel and magnetic stir bar, was charged styrene (410 g, 3.94 mols) and Bis(triphenylphosphine)palladium (II) dichloride (1.2 g, 0.3% wt). The reaction mixture was heated to 70° C. and then trichlorosilane (532.8 g, 3.94 mols) was added dropwise to the reaction mixture. During the addition, the reaction mixture was maintained between 80 to 110° C. After the addition was finished, the reaction mixture was kept at 70° C. for additional two hours. After distillation, >98% pure (1-phenylethyl)trichlorosilane (840 g, 99% purity) was obtained (collected at 78° C./3 mmHg). The product structure was characterized by GC-MS.
