General description
Lithium bis(trimethylsilyl)amide solution (LiHMDS) is generally used in organic synthesis as a non-nucleophilic strong Bronsted base.
Application
LiHMDS can be used as a reagent:
- In the deprotonation and nucleophilic difluoromethylation reactions.
- To synthesize isoquinoline derivatives by the addition of N-iodosuccinimide (NIS) to the α-benzyl tosylmethyl isocyanides.
- To prepare arylboronic acid pinacol esters by the reaction of aryl fluorides with bis(pinacolato)diboron via palladium-catalyzed cross-coupling reaction.
Lithium bis(trimethylsilyl)amide is generally used in organic synthesis as a non-nucleophilic strong Brønsted base. It can be used for salt metathesis reaction for the synthesis of cesium bis(trimethylsilyl)amide (CsHMDS) and lithium fluoride by reacting with cesium fluoride.
