Abstract
Access to the [Me2Si] ansa-bridged permethylmolybdenocene system is provide d by the synthesis of [Me2Si(C5Me4)(2)]MoCl2 from the reaction of MoCl5 wit h a mixture of[Me2Si(C5Me4)(2)]Li-2 and NaBH4, followed by treatment with C HCl3. Comparison with the chemistry of the non-ansa Cp*2MoX(2) system indic ates that incorporation of the [Me2Si] ansa bridge promotes intermolecular C-H and C-C bond activation reactions.
