Reaction Steps

The thus-obtained white solid (2-methylbenzo[e]indenyllithium, 0.94 g, 5.1 mmols) was dissolved in dry tetrahydrofuran/diethyl ether (40 ml, 1/1 v/v). On the other hand, dimethyldichlorosilane (2.60 g, 20.2 mmols) was dissolved in dry tetrahydrofuran/diethyl ether (20 ml, 1/1 v/v), and the resulting solution was dropwise added to the previously-prepared 2-methylbenzo[e]indenyllithium solution at −5° C., over 1 hour. After the addition, this was immediately warmed up to 0° C. with stirring, and further stirred at room temperature for 2 hours. The solvent was removed from the pale yellow suspension under reduced pressure to obtain a yellow paste. The paste was extracted with dry diethyl ether (10 ml×3), and the resulting solution was filtered through a cannula. The filtrate was collected, the solvent was removed under reduced pressure, and this was dried under reduced pressure until it had a constant weight. The thus-obtained viscous yellow oil is 2-methylbenzo[e]indenyldimethylchorosilane (1.35 g, yield 100%).
