Dua, Sujan S. published the artcilePreparation of tris(trimethylsilyl)methyl (“trisyl”) derivatives of silicon, Category: catalysis-chemistry, the publication is Journal of Organometallic Chemistry (1979), 178(1), 75-82, database is CAplus.
Treatment of (Me3Si)3CLi (TsiLi) with appropriate Si halides gave compounds (Me3Si)3CSiRR1X; e.g., TsiSiCl3, TsiSiMeCl2, TsiSiMe2X (X = Cl, OMe), TsiSiPh2X (X = F, Cl, OMe), and TsiSiPhMeH. The trisyl group causes very large steric hindrance to nucleophilic displacements at the Si to which it is attached, so that (unless one or more hydride ligands are present) most of the common displacements at Si do not occur. However, halides can be reduced to hydrides by LiAlH4, and the hydrides can be reconverted into halides in electrophilic displacements by halogens. The presence of even one hydride ligand markedly reduces the hindrance, so that, for example, TsiSiPhHI reacts with refluxing MeOH to give TsiSiPhH(OMe).
