What is N-HEXYLLITHIUM?

Description

n-Hexyllithium [21369-64-2], C6H13Li, Mr 92.11, r 0.766 g/cm3 is a pyrophoric colorless and viscous liquid in the neat state. It is commercially available as a 33 % solution in technical-grade hexane. Its reactivity resembles that of n-butyllithium and it can thus principally be used for the same applications. An advantage is that it does not form gaseous byproducts in deprotonation reactions and on hydrolysis, but liquid hexane instead.

Chemical properties

often supplied as a deep yellow solution (ca 2M) in hexane
