General description
n-Butyllithium (n-BuLi) is an organolithium reagent widely used as a strong base (superbase) in organic synthesis for the preparation of various chemical intermediates. It is also used as a reagent for lithium-halogen exchange and lithium-metal transmetalation reactions. n-BuLi is capable of lithiating carbon acids.
Application
n-Butyllithium (2.0 M in cyclohexane) can be used as:
- A polymerization initiator to synthesize polystyrenes by anionic polymerization of styrene.
- A strong base in the diastereoselective alkylation reactions.
- A reagent to synthesize 2-benzoylpyrroles by reacting benzaldehydes with di(1H-pyrrol-1-yl)zirconium(IV) chloride complex.
Packaging
The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
