Procedure
In an argon atmosphere, to a tetrahydrofuran solution (1 ml) of 52 mg (0.15 mmol) of octaethylcyclotetrasilane was added 0.56 ml (0.15 mmol) of a tetrahydrofuran solution (0.27M) of phenyldimethylsilyllithium, and stirred at 0° C. for 15 minutes. Trimethylchlorosilane in an amount of 108 mg (1.0 mmol) was added, and reacted at room temperature for 3 hours. Hexane (2 ml) and saturated aqueous sodium bicarbonate solution (2 ml) were added, stirred, the hexane layer was separated, and dried with magnesium sulfate. The resulting crude product was purified by a silica gel column chromatography (hexane) to give 39 mg (47% yield) of 2,2,3,3,4,4,5,5-octaethyl-1,1,6,6,6-pentamethyl-1-phenylhexasilane (2).
