抄録

In the presence of SnCl4Bu4N reagent, silyl enol ethers and ketones were α-alkylidenated or α-alkenylated with 1-alkynes. Phenols were ortho-alkenylated using this system. Direct ortfeo-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. Phenol, Vinylation, Alkenylation, 1-Alkyne, Ethyne, SnCl4-Bu3N, Ketone, Silyl.
