Synthesis and Characterization of Methoxylated Oligosilyl Group 4 Metallocenes.

ABSTRACT: New methoxylated oligosilyl-substituted metallocenes were synthesized by the reaction of two oligosilanides with different metallocene dichlorides (M = Ti, Zr, and Hf). The first investigated tris(trimethoxysilyl)silanide [(MeO)₃Si]₃SiK (1) underwent a selective monosubstitution to the respective oligosilyl-decorated metallocenes [(MeO)₃Si]₃SiMClCp₂ (2-4). Surprisingly, the attempted disilylation with this silanide was not possible. However, in the case of titanocene dichloride, a stable radical [(MeO)₃Si]₃SiTiCp₂ (5) was formed. The unsuccessful isolation of bisilylated metallocenes encouraged us to investigate the reactivity of another silanide. Therefore, we synthesized a
