To a yellow suspension of (pentamethylcyclopentadienyl)zirconium trichloride, Cp*ZrCl3, (5.00 g, 15.0 mmol, 1.00 equiv.) in ether (50 mL) was added lithium indenide (1.83 g, 15.0 mmol, 1.00 equiv.). The reaction turned slightly more manila-colored. The mixture was stirred 16 hours and then evaporated in vacuo, leaving yellow solid. The solid was extracted with dichloromethane (30 mL, then 3×5 mL) and the extracts were filtered to give light manila solid and a bright yellow solution. The solution was evaporated in vacuo, leaving yellow crystalline solid. The solid was washed with pentane (20 mL) and dried in vacuo. Yield 5.92 g (96%). 1H NMR(CD2Cl2): δ 2.03 (s, 15H, Me), 6.18 (d, 2H, Ind-H), 6.34 (t, 1H, Ind-H), 7.24 (m, 2H, Ind-H), 7.54 (m, 2H, Ind-H).
