Silyl enol ethers (2) react with trihutyl [(phenylthio) chloromethyl] stannane (1) in the presence of Zinc bromide to give B-phenylthiomethylstannyl ketones (3) in good yields. Silyl dienol ethers (4) mainly give products (5) due to y-attack, under these conditions. S-Stannyl Carbonyl compounds have
