CH3CH2CH2CH2Li
CH3CH2CH2CH2Li, also known as n-butyllithium or 1-butyllithium, is an organolithium compound with the chemical formula C4H9Li. It is a colorless liquid that is highly reactive and pyrophoric, meaning it ignites spontaneously in air. It is typically supplied as a solution in hydrocarbon solvents like hexane, heptane, or cyclohexane due to its instability in pure form. n-Butyllithium is a strong base and a potent nucleophile, making it a widely used reagent in organic synthesis.
The primary application of n-butyllithium is in deprotonation reactions, where it abstracts protons from weakly acidic
