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.

Two-dimensional (2D) semiconducting monolayer transition metal dichalcogenides (TMDCs) have stimulated lots of interest because they are direct bandgap materials that have reasonably good mobility values. However, contact between most metals and semiconducting TMDCs like 2H phase WSe2 are highly resistive
