실험 절차

SiMe2 Cl2(0.69 g, 5.4 mmol) was dissolved in 80 mL of THF. While stirring, lithium 4-(3′,5′-dimethylphenyl)-2-isopropylindenide (2.9 g, 11 mmol) was added as a dry powder and the contents allowed to stir overnight at room temperature. The solvent was removed in vacuo and the residue was taken up in pentane and filtered to removed LiCl salts. The pentane was removed in vacuo to yield a flaky white solid (2.1 g, 67%)
