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
Enol boranes, I, undergo efficient exchange with N-trimethylsilylimidazole, 2, to afford the corresponding trimethylsilyl enol ethers, 3, in good yield under mild conditions. Synthetic routes to enol silyl ethers and enol boranes have received considerable attention recently because of their importa
