실험 절차
Into a 3 liter round-bottom flask fitted with a reflux condenser, addition funnel and magnetic stir bar, was charged 4-methylstyrene (904.4 g, 7.65 mols), VCAT (2.25 g, 50 ppm) and phenothiazine (1.94 g, 1000 ppm). The reaction mixture was heated to 70° C. and then trichlorosilane (1036.6 g, 7.65 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, >98% pure (2-p-tolyl-ethyl)trichlorosilane (1565 g, 6.19 mols) was obtained (collected at 75° C./1 mmHg). The product structure was characterized by GC-MS.
