반응 단계

In the same apparatus and procedures as EXAMPLE 2 above, 14.70 g (100 mmol) of 1,4-dichlorobenzene and 0.027 g (1.0 mmol) of aluminum foil were alkylated with 4.98 g (21.4 mmol) of (2,2-dichloroethyl)trichlorosilane for 1 hour at 80° C. 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 3.33 g of [2,2-bis(2,5-dichlorophenyl)ethyl]trichlorosilane (bp; 161-163° C./1 torr, yield; 59%).
