Epoxidation of Olefins with Alkaline Sodium Bromite in the Presence of Copper Ions

Abstract

Epoxidation of olefins with sodium bromite was st udied in the alkaline aqueous solution. The epoxidation proceeded effectively at room temperature in the presence of small amount of copper ion. No epoxidation occurred without copper ion. It is considered that copper ion is reacted with sodium bromite to give unstable copper(II)bromite. Reaction of epoxidation is proposed as follows.
