Webn-Butyllithium C 4 H 9 Li (abbreviated n-BuLi) ... Alkyl-lithium compounds are stored under inert gas to prevent loss of activity and for reasons of safety. n-BuLi reacts violently with water: C 4 H 9 Li + H 2 O → C 4 H 10 + LiOH. This is an exergonic and highly exothermic reaction. If oxygen is present the butane produced may ignite. WebPropyne is a convenient three-carbon building block for organic synthesis. Deprotonation with n -butyllithium gives propynyllithium. This nucleophilic reagent adds to carbonyl groups, producing alcohols and esters. [6] Whereas purified propyne is expensive, MAPP gas could be used to cheaply generate large amounts of the reagent.
