Application
- Sodium bis(trimethylsilyl)amide, also known as NaHMDS, is a metal dialkylamide reagent that combines both high basicity and nucleophilicity. It is a general reagent used for the enolization of carbonyl compounds.
- It can be used to prepare phosphonium ylides in Wittig reaction.
- NaHMDS solution can also be used as a source of nitrogen in aminomethylation and in the synthesis of primary amines from the corresponding alkyl halides.
