Reaction Steps

In a 70 ml bulb were placed 2.26 g (6 mmol) of the ligand 10-[1-methyl-1-(cyclopentadienyl)ethyl]N-phenyl-5,10-dihydroindeno[1,2-b]indole, prepared in Example 16, and 20 ml of toluene. The obtained mixture was cooled to −50° C. and treated with 7.5 ml (12 mmol) of BuLi 1.6N in hexane. The resulting solution was allowed to warm to room temperature within 1 hour and then it was treated with 1.4 g (6 mmol) of ZrCl4. The solvent was evaporated and the residue was recrystallized from ether, thus yielding 0.55 g of isopropyliden(N-phenyl-5,10-dihydroindeno[1,2-b]indol-10-yl)(cyclopentadienyl) zirconium dichloride (yield=17%).
