In the presence of SnCl4-Bu3N reagent, silyl enol ethers and ketones were α-alkylidenated or α-alkenylated with 1-alkynes. Phenols were ortho-alkenylated using this system. Direct ortho-vinylation of phenols was achieved by treating with ethyne (acetylene gas) at ambient pressure. These syntheses involve carbostannylation reaction where α-stannyl ketones or phenoxytins add to alkynyltrichlorotins giving 1,1-bis(stannyl)alkenes.
