실험 절차

1H NMR (d8-THF): δ 1.4 (d, 12H, Me), 3.22 (s, 4H, bridge CH2), 3.4 (septet, 2H, CHMe2), 5.93 (s, 2H, CH), 6.28 (m, 4H, aromatic CH), 7.08 (t, 2H, aromatic CH), 7.22 (t, 2H, aromatic CH), 7.28 (t, 4H, aromatic CH), 7.66 (d, 4H, aromatic CH) ppm. The dianion was suspended in toluene and cooled to −30° C.; 0.15 g of ZrCl4 (0.64 mmol) were added and the reaction niixture was stirred for 4 hours at 20° C. and then centrifuged. Toluene was discarded and the remaining powder was extracted with CH2Cl2. Centrifugation afforded a mixture of the two isomers rec/meso-1,2-ethylene-bis(1-isopropyl-4-phenyl-2-indenyl)zirconium dichloride, about in a 1:1 ratio.
