Mild oxidation of styrene and its derivatives catalyzed by ionic manganese porphyrin embedded in a similar structured ionic liquid

Without the auxiliary involvement of axial ligands and organic solvents, the ionic manganese porphyrin (1c) with a pyridinium tag embedded in a pyridinium based ionic liquid, [BPy][BF4], efficiently catalyzed the oxidation of styrene and its derivatives under mild conditions, affording high activity/oxide selectivity and good stability even after 5 recycling uses.
