In the presence of TiCl4, trimethylsilyl enol ethers of ketones react smoothly with ketones or aldehydes at room temperature to give the aldol type addition products, β-hydroxyketones, in good yields.

Glucosides and disaccharides are prepared in good yields from 2,3,4,6-tetra-O-benzyl-β-d-glucopyranosyl fluoride and hydroxy compounds in the presence of stannous chloride and silver perchlorate. In most cases, α-glucosides are predominantly (α⁄β=80⁄20∼92⁄8) obtained.

In the presence of a catalytic amount of bis(acetylacetonato)cobalt(II), various olefins react smoothly with molecular oxygen and phenylsilane at room temperature to afford the corresponding alcohols in good yields under neutral conditions.
