that a manganese (III) porphyrin cage reacts with the oxidant iodosylbenzene to form an inside iodosylbenzene complex, which is converted into a manganese(V)oxo complex in which the oxo group is located inside the cage (left). It reacts within the cage with alkenes to form epoxides. When the cage is blocked by methyl groups the reaction with iodosylbenzene and the formation of the manganese(V)oxo complex
