Identifying the True Catalyst: A Mn(II) Salt versus Mn(II) Complexes in Epoxidation with m‐Chloroperbenzoic Acid

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
The oxidant meta‐chloroperbenzoic acid (m‐CPBA) is used widely for the epoxidation of alkenes, yet its efficiency is often limited under ambient conditions. In this study we investigate the catalytic activity of a Mn(II) salt and mononuclear Mn(II) complexes, two of which are reported here for the first time, in the epoxidation of alkenes with m‐CPBA ...
