Source: Vy M. Dong and Diane Le, Department of Chemistry, University of California, Irvine, CA This experiment will demonstrate a simple technique to titrate and obtain an accurate concentration of the organolithium reagent, n-butyllithium (n-BuLi). Organolithium reagents are extremely air- and moisture-sensitive and proper care must be taken to maintain the quality of the reagent so that it may be used successfully in a reaction. The n-BuLi titration experiments should be performed regularly...

FAQs
The polarized carbon–lithium bond gives the carbon center strong carbanion character. This electronic arrangement accounts for two complementary behaviors: the carbon can remove protons from weakly acidic C–H bonds, and it can act as a carbon nucleophile in bond-forming reactions. Consequently, the compound can both generate reactive intermediates and contribute carbon to subsequent synthetic transformations.
Its strong basicity allows tert-butyllithium to remove protons that less powerful bases may not abstract efficiently. Deprotonation produces an organolithium intermediate that can undergo further synthetic reactions. This capability is especially valuable when chemists need to activate a particular C–H bond during a multistep sequence or use deprotonation to direct regioselective functionalization.
Lithium–halogen exchange provides a route to organolithium intermediates from halogen-containing starting materials. Once generated, those intermediates can participate in reactions that form new carbon–carbon bonds. This makes the exchange process useful for converting an existing functional group into a more reactive synthetic handle and for incorporating organolithium chemistry into multistep molecule construction.
Reactions require rigorously dry, oxygen-free conditions because tert-butyllithium reacts rapidly with moisture and oxygen. Chemists also often use low temperatures to help manage its high reactivity. Specialized handling techniques are necessary because exposure to air can cause spontaneous ignition, making control of the reaction environment essential for both safety and reproducible synthetic outcomes.
A synthesis first uses the reagent to generate a reactive organolithium intermediate, either by deprotonating a weakly acidic C–H bond or through lithium–halogen exchange. That intermediate then serves as a basis for further transformation, including carbon–carbon bond formation. The approach is therefore useful for linking activation and construction steps within a multistep synthesis.
Chemists choose tert-butyllithium when the synthesis requires very strong basicity, rapid generation of an organolithium intermediate, or carbon-nucleophile behavior. Its reactivity can enable deprotonation of weakly acidic C–H bonds and support lithium–halogen exchange. These properties are particularly relevant when regioselective functionalization or new carbon–carbon bond formation is needed.
