摘要：

: Internal alkynes underwent a novel oxidation with aqueous hydrogen peroxide catalyzed by peroxo-tungsten compounds under two-phase conditions using chloroform as the solvent, giving α,β-epoxy ketones and a,0-unsaturated ketones as principal products. The epoxidation of α,β-unsaturated ketones by this catalyst-ox-idant system appeared to involve the electrophilic attack of the peroxo species to the double bond. © 1990, American Chemical Society.
