실험 절차

To a solution of 2.62 g (13.4 mmol) of (3-trimethylsiloxypropyl)-cyclopentadiene in ether, 5.36 ml of a 2.5 M (13.4 mmol) butyl lithium solution in hexane is added at −78° C. The immediate formation of a white solid is observed. The reaction is maintained under stirring for 2 hours; then, the white suspension is brought to dryness, the resulting solid is washed twice with hexane and a powdery white solid is obtained. (2.3 g, 11.4 mmol. Yield: 85%).
