A recyclable Fe3O4-supported cobalt nanocatalyst for the epoxidation of olefins using aqueous hydrogen

Abstract

A novel and green method of olefin epoxidation was developed by using aqueous hydrogen peroxide as the terminal oxidation agent over Co-Fe3O4 magnetic nanoparticles catalyst in acetonitrile medium. This process showed excellent conversion and selectivity toward both terminal and substituted olefins. Co-Fe3O4 magnetic nanoparticles could be recycled and reused without significant loss of catalytic activity in this transformation.
