Oxygen transfer in electrophilic epoxidation probed by (17)O NMR: differentiating between oxidants and role of spectator metal oxo

Peroxide compounds are used both in laboratory and industrial processes for the electrophilic epoxidation of olefins. Using NMR-spectroscopy, we investigate why certain peroxides engage in this type of reaction while others require activation by metal catalysts, e.g. methyltrioxorhenium (MTO). More...
