Reaction Steps

Under the nitrogen protection, 0.24 gram (0.001 mole) of 5,8-dimethyl-5,10-dihydroindeno[1,2-b]indolyllithium is dissolved in 20 mL of diethylether. The solution is slowly added to zirconium tetrachloride (0.12 gram, 0.0005 mole) slurry in 20 mL of diethylether. The mixture is stirred at 25° C. for two hours, filtered, washed with diethylether and dried under vacuum, yielding 0.23 gram of Catalyst III.
