Description
Summary:An easy and efficient method for preparation of meso-pyridinylporphyrins covalently bound by N-alkylation to polystyrene is provided. Catalytic efficiency of Mn 3+ or Fe 3+ metallocomplexes of pyridinium-porphyrin-polystyrene catalysts in styrene/ t-butyl hydroperoxide or hydrogen peroxide/pyridine or N-methylimidazole/dichloromethane system is described. The effect of pyridiniumporphyrin isomerism on catalyst stability is studied.
