Example 17 [Dimethylsilylbis(2,4-dimethylcyclopentadienyl)zirconium dichloride] All reactions were carried out under an inert gas atmosphere. Moreover, the reaction solvent used was one that had been dried in advance. In a 200 ml glass reaction vessel, 3.67 g (15 mmol) of dimethylbis(2,4-dimethylcyclopentadienyl)silane
was dissolved in 50 Ill of tetrahydrofuran, and then a 1.57M hexane solution of lobetillithium 21a+1 was slowly added dropwise under water cooling. After stirring at room temperature for 2 hours, a yellow suspension ? eL (L12 [Me2Si(MB2-Cs
Hz) 2]) was obtained. In a 500 ml glass reaction vessel, 3.5 g (15 mmol) of zirconium tetrachloride was cooled to -78 DEG C., and 200 ml of tetrahydrofuran was added. Next, the above yellow suspension was slowly added dropwise at -78°C. After slowly returning to room temperature, heating was carried out for 4 days. After cooling, the solvent was distilled off from the yellow-orange solution, 300 Ill of methylene chloride was added, the white solid produced was filtered, and the resulting filtrate was concentrated to dryness to obtain a warm white solid. Recrystallization was performed using a toluene-hexane mixed solvent to obtain 0.23 g of white crystals. The physical properties of this compound are shown below. Note that the IR spectrum is based on the KBr method,
