Description: Lithium Diisopropylamide is a non-pyrophoric hindered non-nucleophilic strong base widely used for the generation of carbanions1, including the initiation of anionic polymerization2. This product circumvents the generation and evolution of butane associated with the preparation of Lithium Diisopropylamide by the reaction of n-butyllithium and diisopropylamine.

Description: Lithium Hexamethyldisilazide is a non-pyrophoric strong base, widely employed in organic synthesis as a metalation agent. The principle advantages of this reagent are the improved selectivity obtained in deprotonation reactions and the enhanced thermal stability. It is employed as a base in generating enolates for the preparation of lactone precursors. Lithium Hexamethyldisilazide is offered in THF solution and therefore, is very easy to transfer from shipping container to storage or a reactor. Lithium Hexamethyldisilazide is a more stable base than Lithium Diisopropylamide or lithium diisopropylamide.
