실험 절차

In a 500-ml glass reaction vessel, 4.3 g (33 mmol) of 2-methylindene was dissolved in 80 ml of tetrahydrofuran. 21 ml of a 1.6 M hexane solution of n-butyllithium was slowly added dropwise to the reaction vessel while cooling. The mixture was stirred at room temperature for one hour, and then cooled again. To this mixture, 2.1 g of dimethyldichlorosilane was slowly added dropwise, and the resulting mixture was stirred at room temperature for 12 hours. 50 ml of water was added to the mixture, and the organic phase was fractionated and dried to give 3.5 g of dimethylbis-(2-methylindenyl)silane.
