prop-1-ynyllithium
Sign in to saveAlso known as 1-propynyllithium, Propynyllithium
Propynyllithium is an organolithium compound with the chemical formula . It is a white solid that is soluble in 1,2-dimethoxyethane, and tetrahydrofuran. To preclude its degradation by oxygen and water, propynyllithium and its solutions are handled under inert gas (argon or nitrogen). Although commonly depicted as a monomer, propynyllithium adopts a more complicated cluster structure as seen for many other organolithium compounds.

Propynyllithium is an organolithium compound with the chemical formula . It is a white solid that is soluble in 1,2-dimethoxyethane, and tetrahydrofuran. To preclude its degradation by oxygen and water, propynyllithium and its solutions are handled under inert gas (argon or nitrogen). Although commonly depicted as a monomer, propynyllithium adopts a more complicated cluster structure as seen for many other organolithium compounds.
==Synthesis== Various preparations of propynyllithium are known, but the most expeditious route starts with 1-bromopropene: CH3CH=CHBr + 2 BuLi → CH3C≡CLi + 2 BuH + LiBr
