Participants

Reaction Steps

2,5-Dimethyl-4-(3,5-dimethylphenyl)indene (2.1 g, 8.4 mmol), prepared as described under (f) above, was dissolved in 60 ml of pentane. To this solution was added 3.4 ml of nBuLi (2.5 M in hexane) and the reaction was stirred for two hours at room temperature. A white solid precipitated from solution and was collected by frit filtration and washed with additional pentane. Yield: 1.6 g (74%).
