実験手順

In the same apparatus and procedures as EXAMPLE 2 above, 26.3 ml (230 mmol) of 2,3-dichlorobenzene and 1.23 g (9.2 mmol) of aluminum chloride were alkylated with 11.91 g (45.7 mmol) of (2,3-dichlorobutyl)trichlorosilane for 20 min at 90° C. The aluminum chloride catalyst was quenched with POCl3 and then stirred for another 30 min 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 5.06 g of [3,3-bis(2,4-dichlorophenyl)butyl]trichlorosilane (bp; 186-190° C./0.5 torr, yield; 23%).
