A colorless or white solid, it is encountered mainly as a solution in tetrahydrofuran (THF).
[1] Solutions of vinyllithium are prepared by lithium-halogen exchange reactions.
A halide-free route entails reaction of tetravinyltin with butyllithium: The reaction of ethylene and lithium affords vinyl lithium and lithium hydride, together with other organolithium compounds,[1] Like most organolithium compounds, vinyllithium crystallizes from THF as a cluster compound as a cubane-type cluster.
[3] It adds to ketones compounds to give allylic alcohols.
[4] Vinyl magnesium bromide, a Grignard reagent, is in many ways easier to generate in the laboratory and behaves similarly to vinyllithium.
