Description and Uses
Sodium bis(trimethylsilyl)amide is a synthetically useful reagent in that it combines both high basicity and nucleophilicity, each of which may be exploited for useful organic transformations such as selective formation of enolates, preparation of Wittig reagents, formation of acyl anion equivalents, and the generation of carbenoid species. As a nucleophile, it has been used as a nitrogen source for the preparation of primary amines.It is useful as a sterically hindered base and as a nucleophile.
