2,5-Dimethyl-4-phenylindene → Lithium[2,5-dimethyl-4-phenylindenide]

Participants

Reaction Steps

2,5-Dimethyl-4-phenylindene (1.3 g, 5.9 mmol), prepared as described under (a) above, was dissolved in 100 ml of pentane. To this solution was added 2.4 ml of nBuLi (n-butyl lithium, 2.5 M in hexane) and the reaction was stirred five hours at room temperature. A yellow-white solid precipitated from solution and was collected by frit filtration and washed with additional pentane. Yield: 1.2 g (98%).
