Epoxidation catalysed by MnIIITPPCl using dioxygen activated by a system containing N-hydroxyphthalimide and styrene, 2-norbornene or indene

Abstract

The catalytic epoxidation of alkenes by molecular oxygen activated in the system containing N-hydroxyphthalimide (NHPI) and active alkenes such as styrene, 2-norbornene or indene is reported. The transient intermediates, alkyl hydroperoxides formed by autoxidation of NHPI and the active alkenes are proposed as oxygen sources which transfer mono-oxygen to Mn^IIITPPCl.
