Procedure

Dimethylsilylenebis(2-methyl-4,5,6,7-tetrahydroindenyl)zirconium dichloride was prepared by first synthesizing dimethylsilylenebis(2-methylindenyl)zirconium dichloride as in Example-A13, and the latter in an amount of 1.0 g was dissolved in 150 ml of dichloromethane and was introduced in an autoclave of 500 ml capacity in which it was reacted in the presence of 0.1 g of platinum oxide added with hydrogen under a pressure of 50 kg/cm2G at room temperature for 5 hours. The platinum oxide catalyst was then removed and the solvent used was removed in vacuo whereby a solid was obtained, which solid was extracted with toluene and recrystallization was conducted to give 0.32 g of dimethylsilylenebis(2-methyl-4,5,6,7-tetrahydroindenyl)zirconium dichloride desired.
