Mild and efficient ring opening of epoxides catalyzed by potassium dodecatungstocobaltate(III)

Abstract

Efficient ring opening of epoxides under mild conditions is reported. Potassium dodecatungstocobaltate(III) trihydrate was used as an efficient catalyst for the alcoholysis and acetolysis of epoxides. Conversion of epoxides to thiiranes was also performed efficiently in the presence of this catalyst. © Springer-Verlag 2005.
