Alkene Epoxidation with Hydrogen Peroxide - in the Presence of Further Catalysts

Alkene Epoxidation with Hydrogen Peroxide - in the Presence of Further Catalysts 

A second class of catalysts comprises perfluorinated ketones such as hexafluoro-acetone [38] and perfluoro-2-octanone ]39]. This class of catalyst is assumed to reversibly form peroxyhemihydrates when exposed to hydrogen peroxide ]40] the latter are the active oxygen-transfer agents. Oxygen transfer to the substrate is accompanied by formation of the ketone s hydrate, which, in equilibrium, regenerates the fluoroketone catalyst.
