The products of C-vinylation were prepared in 52-65% yield by the reaction of secondary nitroalkanes with acetylene in DMSO-KOH.

Trimethyl(vinyl)stannanes undergo a rapid tin-lead exchange with lead tetraacetate to give high yields of unstable vinyllead triacetates.Solutions of vinyllead triacetates produced in this way react with soft carbon nucleophiles such as β-dicarbonyl compounds and nitronate salts to give moderate to good yields of C-vinylated products.The method is more economical in terms of vinyl group incorporation than previously reported vinylations by vinyllead triacetates.An even faster tin-lead exchange has been observed when trimethyl(vinyl)stannanes are treated with lead tetrabenzoate, and vinylations with this reagent proceeded in significantly higher yields.
