Oxidation of cycloalkanes with potassium peroxosulfate catalyzed by montmorillonite-immobilized metal tetrapyridylporphyrin complexes

The oxidation of 1,3-dimethyladamantane and cyclooctane with potassium pero xosulfate catalyzed by manganese and iron complexes of alkylated tetrapyrid ylporphyrin which was either dissolved in a reaction medium or adsorbed on a layered aluminosilicate was studied. The Mn3+ porphyrin complex immobiliz ed in the interlamellar space of montmorillonite modified with titanium hyd roxide clusters was found to enhance the catalytic activity and stability a gainst oxidative degradation.
