Reaction Steps

2.16 g (5.69 mmol) of the organocomplex (cyclopentadienyl)(trimethylsiloxyethylcyclopentadienyl) zirconium dichloride was added to a suspension of 2.9 g of Silica XPO 2407 in 75 ml of dry toluene at room temperature; the suspension immediately acquired a greenish-yellow color. The sample was maintained under continuous stirring at room temperature for 48 hours. The yellow solution was separated from the solid by filtration. The solution was brought to dryness and, after washing with three fractions of 15 ml of hexane, a dusty white solid was obtained. (0.57 g Yield: 30%) 1H-NMR: (Cl3CD): 1.65 (m,1H), 2.95 (t,2H), 4.05 (m,2H), 6.32 (m,2H), 6.35 (m,2H), 6.5 (s,5H).
