摘要

Summary: Internal alkynes underwent a novel oxidation with aqueous hydrogen peroxide catalyzed by peroxotungsten compounds under two-phase conditions using chloroform as the solvent, giving a,@-epoxy ketones and a,@-unsaturated ketones as principal products. The epoxidation of a, p-unsaturated ketones by this catalyst-oxidant system appeared to involve the electrophilic attack of the peroxo species to the double bond.
