Vinyl tributyltin is an organotin compound with the formula Bu3SnCH=CH2 (Bu = butyl). It is a white, air-stable solid. It is used as a source of vinyl anion equivalent in Stille coupling reactions.[1][2] As a source of vinyltin reagents, early work used vinyl trimethyltin,[3] but trimethyltin compounds are avoided nowadays owing to their toxicity.


The compound is prepared by the reaction of vinylmagnesium bromide with tributyltin chloride.[4] It can be synthesized in the laboratory by hydrostannylation of acetylene with tributyltin hydride. It is commercially available.
