摘要：

The title compound, 1, has been made by an improved method involving treatment of (o-MeC6H4Me2Si)(3)CH with LiBu in the presence of tetramethylethylenediamine in a hexane-heptane mixture at room temperature followed by crystallization of the product from a mixture of heptane and tetrahydrofuran (THF). In contrast to solid Li{C(SiMe2Ph)(3)}(THF), which has a molecular structure with a C-Li bond and a Ph-Li interaction, 1 contains a discrete planar carbanion with no such interaction.
