WebAnionic Initiator and Polymerization. The major industrial application of butyllithium is that of an anionic initiator for the manufacture of polyisoprene, polybutadiene and butadiene/styrene copolymers, all of which have gained considerable importance to the rubber and plastics market. Moreover, butyllithium has become a very valuable tool in ... WebWhen n -butyllithium is exposed to air or moisture during preparation or storage, its concentration can be diminished, leading to an inaccurate amount being used in a reaction. The use of partially degraded n -butyllithium solutions can cause poor yield, create a greater number of byproducts, require more complicated and time-consuming ...
WebApr 22, 2011 · Methyllithium is a strong basic and a powerful nucleophile. Compared to another synthetically important organolithium compound, n -butyllithium, methyllithium reacts slowly with tetrahydrofuran at room temperature.

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 → … See more Butyllithium is a strong base (pKa ≈ 50), but it is also a powerful nucleophile and reductant, depending on the other reactants. Furthermore, in addition to being a strong nucleophile, n-BuLi binds to aprotic Lewis bases, such as ethers and tertiary See more • Propynyllithium, an organometallic compound. See more Butyllithium is principally valued as an initiator for the anionic polymerization of dienes, such as butadiene. The reaction is called "carbolithiation": 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 → C4H10 + LiOH This is an exergonic and highly exothermic reaction.
