n-Butyllithium C4H9Li (abbreviated n-BuLi) is an organolithium reagent. It is widely used as a polymerization initiator in the production of elastomers such as polybutadiene or styrene-butadiene-styrene (SBS). Also, it is broadly employed as a strong base (superbase) in the synthesis of organic compounds as … See more n-BuLi exists as a cluster both in the solid state and in a solution. The tendency to aggregate is common for organolithium compounds. The aggregates are held together by delocalized covalent bonds between lithium … See more The standard preparation for n-BuLi is reaction of 1-bromobutane or 1-chlorobutane with Li metal: 2 Li + C4H9X → C4H9Li + LiX (X = Cl, Br) If the lithium used for this reaction contains 1–3% sodium, the reaction proceeds more quickly than if pure … See more Alkyl-lithium compounds are stored under inert gas to prevent loss of activity and for reasons of safety. n-BuLi reacts violently with water: C4H9Li + H2O → … See more • Propynyllithium, an organometallic compound.
