Lithium bis(trimethylsilyl)amide Chemical Properties,Uses,Production

Chemical Properties

light yellow to yellow crystalline powder

Uses

Lithium bis(trimethylsilyl)amide is used as nonnucleophilic base to generate kinetic ketone and ester enolates. It is considerably more selective than LDA and undesired reductions (e.g., of nonenolizable ketones observed in the case of LDA) can be avoided by using LHMDS.
