General description
Lithium diisopropylamide solution (LDA) is a sterically hindered non-nucleophilic strong base widely used in organic synthesis.
Application
Lithium diisopropylamide solution (LDA) can be used:
- As an initiator in the anionic polymerization of
D ,L -lactide and methyl methacrylate. - To facilitate ester enolization.
- To convert carboxylic acids to enediolate intermediates for preparing trifluoromethyl ketones.
- In ortho-lithiation of arylsulfonyloxazolidinones to prepare N-substituted saccharin analogs.
- To catalyze ortholithiation and Fries rearrangement of aryl carbamates.
- As a promoter in the isomerization of allylic ethers to (Z)-propenyl ethers.
Packaging
The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
