摘要

Abstract Treatment of (Me 3 Si) 3 CLi (“trisyl” lithium, TsiLi) with appropriate silicon halides has given a range of compounds of the type (Me 3 Si) 3 CSiRR′ X; eg, TsiSiCl 3, TsiSiMeCl 2, TsiSiMe 2 X (X= Cl, OMe), TsiSiPh 2 X (X= F, Cl, OMe), and TsiSiPhMeH. The trisyl group causes very large steric hindrance to nucleophilic displacements at the silicon to which it is attached, so that (unless one or more hydride ligands are present) most of the common ...
