실험 절차

In a 500 ml glass reactor, 4.3 g (33 mmole) of 2-methylindene was dissolved in 80 ml of tetrahydrofuran, to which 21 ml of 1.6M n-butyllithium in hexane was slowly added under cooling. After the mixture was stirred at room tempearture for 1 hour, it was cooled again, and 2.1 g of dimethyldichlorosilane was added dropwise. After the mixture was stirred at room temperature for 12 hours, 50 ml of water was added, and the organic phase was separated and dried to give 3.5 g of dimethylbis(2-methylindenyl)silane.
