This paper talks about the important role of methyltrioxorhenium (MTO). MTO has the molecular formula CH-ReO and it has a high Lewis-acidity It reacts with H2O2 to be transformed in a multistep reaction into a hydroperoxo complex, which is an exceptionally selective epoxidizing agent. It was shown that the alkyl groups of MTO are the most important part of the compound because it monitors the alkene oxidation while remaining coordinated to MTO. On the other hand, the addition of methyl-cleaving reagents halts the activity immediately. In this way inactive perrhenate (ReO4−) is formed in addition of base.

This paper cited Herrmann's because it involves comparing three different heterocyclic amine additives in the MTO catalyzed epoxidation of olefins using aqueous hydrogen peroxide.
