Reaction Steps

It was worked according to the procedure described at point (c) of example 1 except that, instead of 2,2-bis(3-trimethylsilyl-indenyl)propane, 20 mmol of the dilithium salt of 2,2-bis(3-isopropyl-indenyl)propane was used, and that the product was recrystallized from DME. Pure rac-isopropylidene-bis(3-isopropyl-indenyl)zirconium dichloride was obtained. 1H-NMR (toluene-d8, 30° C.) δ: 7.34 (m.4H); 6.98 (m,2H); 6,69 (m,2H); 5.78 (s,2H); 3.14 (sept,2H); 1.81 (s,6H); 1.20 (d,12H).
