Uses
Trimethylsilylmethyllithium is a reagent used in the methylenation of carbonyl compounds; reacts with carboxylic
acid derivatives to provide α-silyl ketones; synthesis of allylsilanes. It participates in the reactions of Peterson Alkenation, Reaction with Carboxylic Acid Derivatives, Other Electrophiles, etc.
Preparation
Trimethylsilylmethyllithium is obtained by reaction of (chloromethyl)-
trimethylsilane with lithium metal in an inert solvent. It is
also available by displacement of a heteroatom group based on
sulfur, silicon, or tin.
