Abstract

In the presence of a catalytic amount of nickel (II) complex, silyl enol ethers and silyl ketene acetals are smoothly oxygenated by the combined use of molecular oxygen and aldehyde to afford α-siloxy carbonyl compounds via possible intermediates, siloxy epoxides. And on treatment of the α-siloxy carbonyl compounds with potassium fluoride α-hydroxy carbonyl compounds are obtained in good to high yields.
