正丁基锂（n-BuLi）是一种有机锂试剂，通常用作有机合成中的强碱。它也用作各种锂碱（如氨基锂、乙炔锂和烷氧基锂）的锂源。该n-BuLi是聚α-烯烃（PAO）/己烷溶剂混合物中的溶液，被认为是非自燃性的，使用EPA的SW-846测试方法1050进行了证明。
n-BuLi can be used as a strong base to form corresponding lithium salts by the deprotonation of nitrogen, oxygen, phosphorus, and carbon acids. Heterocyclic compounds, such as furans, thiophenes, oxazoles, pyrroles, etc, can be lithiated α to the ring heteroatom using n-BuLi. These lithiated salts react in situ with alkyl halides to obtain useful organic compounds by the formation of the C-C bond. n-BuLi is also a useful reagent for lithium–halogen exchange reactions. Synthesis of various other useful reagents such as lithium diisopropylamide (LDA) and diphenylphosphine is done by in situ reaction with n-BuLi In the polymerization of dienes, n-BuLi is employed as an initiator.
The product is also used in the following reactions:
Anionic rearrangement reactions
Metal-halogen interchange and transmetalation reactionsElimination reactions[1,2]- and [1,4]-Wittig rearrangement reactionAnionic homo-Fries rearrangement reactionAsymmetric carbolithiation
PAO/己烷中的n-BuLi配方：使用EPA的SW-846测试方法1050证明被视为非自燃性保持与传统n-BuLi试剂相同的反应性与传统锂化添加剂（如KO t Bu或TMEDA）兼容比传统n-BuLi试剂更稳定
