Cyclic silyl enol ethers were successfully cleaved by EtOK to generate the corresponding enolates. Reactions with EtOK were faster and the corresponding enolates could be trapped by electrophiles and oxidants to give the kinetic products exclusively.

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
