α-Lithioalkoxysilanes [RO(Me2)Si]CH(Li)(X), where R=Me or Et and X=H or SiMe3, react with carbonyl compounds in hydrocarbon solution to produce alkenes in moderate to high yield via Peterson-type reactions. For X=SiMe3, the corresponding vinylsilane

Ether cleavage of THF at low temperature affords halide-free neohexyllithium in a two-step reaction via insertion of in situ formed ethylene into the C-Li bond of tert-butyllithium. The crystal structure analysis reveals the formation of tetrameric T
