Procedure

The general procedure of Example A is followed. 8-Methyl-5, 10-dihydroindeno[1,2-b]indole reacts with n-butyllithium and the product then reacts with trimethylchlorosilane to form 5-trimethylsilyl-8-methyl-5, 10-dihydroindeno[1,2-b]indole. The later reacts with n-butyllithium to form a lithium salt, which reacts with zirconium tetrachloride to give Catalyst IV.
