실험 절차

In the same apparatus and procedures as EXAMPLE 2 above, 25.2 ml (282 mmol) of benzene and 0.80 g (6.0 m) of aluminum chloride were alkylated with 6.60 g (28.2 mmol) of (1,2-dichloroethyl)trichlorosilane for 20 min at 70° C. The aluminum chloride catalyst was quenched with POCl3 and then stirred for another 1 hour to complete the deactivation. Freshly distilled hexane(50 ml) was added to the reaction mixture and insoluble solids in hexane were filtered from the organic soultion. After hexane and benzene were distilled, the reaction products were vacuum distilled to give 4.82 g of (2,2-diphenylethyl)trichlorosilane (bp; 117° C./0.5 torr, yield; 54%).
