MgO powders activated in vacuo at 400°C and impregnated with nitrobenzene were investigated by ESR spectroscopy. The formation of Mn4+ centers due to electron transfer between nitrobenzene and impurity centers was established. Liquid impregnation yields substantially fewer nitrobenzene anion radicals than vapor-contact between the catalyst and nitrobenzene.
