Description and Uses

tert-Butyllithium solution (tert-BuLi) is an organolithium compound, used as a strong base in organic chemistry. It facilitates lithium-halogen exchange reaction and also can be employed in the deprotonation of C-H compounds and amines. it has applications in organic synthesis since it is a strong base, capable of deprotonating many carbon molecules, including benzene. tert-Butyllithium is available commercially as hydrocarbon solutions; it is not usually prepared in the laboratory. Its synthesis was first reported by R. B. Woodward in 1941.

There are no commercial uses of t-butyllithium, but it is used as a polymerization initiator and as a metalating agent in the laboratory.
Alkylating and metalating agent. Reagent for the introduction of the tert-butyl group.
tert-Butyllithium (t-BuLi) is the most reactive of the commercially available organolithium reagents. It is supplied as a standard solution in hydrocarbon solvents, usually in a bottle sealed with a septum.
