Chloro-9-fluorenyldiphenylsilane (3a) and 9-fluorenyltris(trimethylsilyl)silane (3b) have been prepared by the reaction of the corresponding halosilanes with 9-fluorenyl lithium.The chloro substituent in 3a can be exchanged for other functional groups.With alkaline conditions cleavage of the fluorenyl-silicon bond may happen.The molecular structures of 3b and 9-fluorenyldiphenylsilanole (6a) have been determined by X-ray diffraction.In both compounds the substituents at the Cfluorenyl-Si bond are exactly staggered.The fluorenyl group in 3b is slightly folded, the Cfluorenyl-Si bond is lengthened to 194.7 (4) pm.
