Organolithium compounds, molecules containing a carbon–lithium bond, are excellent precursors for building new carbon–carbon and other carbon–heteroatom bonds. They are widely utilized in both academia and industry for their applications in polymer synthesis, pharmaceuticals, and general organic synthesis.
A conventional method for generating organolithium compounds is done by reacting organohalide compounds, molecules containing a carbon–halogen bond, with lithium metal in an organic solvent. For example, a reaction between 1-bromobutane and lithium metal produces n-butyllithium.
Organolithiums are typically unstable and are therefore rapidly converted into a new product in situ after generating them.
