Participants

Reaction Steps

5.45 g (20 mmol) of 2,2-bis(indenyl)propane prepared according to the procedure of example 1 was dissolved in 100 ml of ether. The solution thus obtained was taken to -20° C., and 22 ml of a 2.0 M solution of n-butyl-lithium in pentane was added, thus giving a suspension of dilithium-2,2-bis(indenyl)propane. 8.77 g (30.85 mmol) of dilithium 2,2-bis(indenyl)propane was dissolved in 100 ml of ether, and 10 ml of Me3SiCl (excess) was added at a temperature of -40° C. The resulting mixture was allowed to return to room temperature. The organic phase was then separated off, the solvent removed and the product dried in vacuo. 1H-NMR
