non-chembox sections

edit

Tris(trimethylsilyl)methyllithium is a reagent used to introduce the extremely bulky tris(trimethylsilyl)methyl (trisyl) ligand or functional group on to compounds/molecules.

Structure

edit

The crystal stucture of the tetrahydrofuran adduct consists of [Li(thf)4]+ cations and [Li{C(SiMe3)3}2] anions.[1]

Synthesis/Preparation

edit

Tris(trimethylsilyl)methyllithium can be prepared by the lithiation of tris(trimethylsilyl)methane by methyllithium in a mixture of tetrahydrofuran and diethyl ether.[2]
