• Butyl lithium may refer to one of three isomeric organolithium reagents used in chemical synthesis: n-Butyl lithium, sec-Butyl lithium, tert-Butyl lithium.
• n-Butyllithium (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).
• Butyllithium is commercially available as solutions (15%, 25%, 2 M, 2.5 M, 10 M, etc.) in alkanes such as pentane, hexanes, and heptanes. Solutions in diethyl ether and THF can be prepared, but are not stable enough for storage.
• Although it is a colourless liquid, n-butyllithium is usually encountered as a pale yellow solution in alkanes.
• 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 and the terminal carbon of the butyl chain.
• The standard preparation for n-BuLi is reaction of 1-bromobutane or 1-chlorobutane with Li metal.
• If the lithium used for above reaction contains 1-3% sodium, the reaction proceeds more quickly than if pure lithium is used. Solvents used for this preparation include benzene, cyclohexane, and diethyl ether.
• One of the most useful chemical properties of n-BuLi is its ability to deprotonate a wide range of weak Brønsted acids. t-Butyl lithium and s-butyl lithium are more basic.
• Butyl lithium reacts with some organic bromides and iodides in an exchange reaction to form the corresponding organo lithium derivative.
• sec-Butyl lithium is an organo metallic compound with the formula CH3CHLiCH2CH3, abbreviated sec-BuLi or s-BuLi. This chiral organo lithium reagent is used as a source of sec-butyl carbanion in organic synthesis.
• sec-BuLi react with carbonyl compounds and esters to form alcohols. With copper(I) iodide sec-BuLi forms lithium di-sec-butylcuprates.
• tert-Butyl lithium is a chemical compound with the formula (CH3)3CLi. As an organo metallic compound, it has applications in organic synthesis (see also Grignard reaction) since it is a sufficiently strong base to deprotonate many carbon acids, including benzene.
• A common use of simple commercially available organolithium compounds (like n-BuLi, sec-BuLi, t-BuLi) is as very strong bases.
