A series of Mn III porphyrins progressively halogenated in the electrophilic pathway of addition and a stereospecific pathway of oxygen insertion, the former being disfavoured Ξ²-pyrrolic positions was employed to catalyse the epoxidation of cis-stilbene by iodosylbenzene, and to study by electron-wi

## Abstract The asymmetric epoxidation of unfunctionalised olefins to epoxides is realised by using manganese(III) complexes stabilised on nanocrystalline magnesium oxide in the presence (1__R__,2__R__)‐(βˆ’)‐diaminocyclohexane as a chiral ligand in good yields and up to 91 % enantiomeric excess.
