Webn-Butyllithium (n-BuLi) is an organolithium reagent commonly used as a strong base in organic synthesis. It is also used as a lithium source for a wide range of lithium bases, such as lithium amides, acetylides, and alkoxides. tert-butyllithium is a pyrophoric substance, meaning that it spontaneously ignites on exposure to air. Air-free techniques are important so as to prevent this compound from reacting violently with oxygen and moisture: t-BuLi + O2 → t-BuOOLi t-BuLi + H2O → t-BuH + LiOH The solvents used in common commercial preparations are themselves flammable.
