Procedure

A solution of lithium fluorene from Example 4 was slowly added dropwise at 0° C., by means of a septum and a syringe, to a solution of chloro-2-indenyl-dimethylsilane (2.85 g, 0.0136 mol.) according to Example 1 in 20 ml of diethyl ether. After 2 hours' stirring at 25° C., the resulting LiCl was filtered off. The solvent was removed from the filtrate and the beige-colored residue was dissolved in hot ether/petroleum ether and crystallized at −30° C. 3.45 g (75%) of fluorenyl-2-indenyldimethylsilane were obtained in the form of a colorless solid. M.p.: 125° C.
