Procedure

In a 100 ml glass-autoclave were introduced 0.66 g of rac-isopropylidene-bis(3-t-butyl-indenyl)zirconium dichloride, 40 mg of PtO2 and 50 ml of CH2Cl2. 5 atm of H2 were pressurized in and the mixture was stirred for 4 hours at room temperature. The mixture was filtered, the filtrate brought to dryness and 0,56 g of a yellow solid was isolated, which was further purified by washing with hexane and Et2O. 0,22 g of a yellow powder were thus obtained. 1H-NMR (CDCl3): 5.3(s), 2.6-2.9(m), 2.2-2.4(m), 1.85(s), 1.4-1.8(m), 1.3(s).
