Abstract: Nitro substituted iron-phthalocyanines on Y zeolite are synthesized via a ligand exchange reaction starting. from a mixture of solids containing ferrocene, 4-nitro-1,2-dicyanobenzene and dry Y zeolite. The nature and loading of the catalyst is verified by Vis-NIR and solid state C-13-NMR. Purification by soxhlet extraction demonstrates that the nitro-substituted phthalocyanines are not located in the supercages but are adsorbed at the outer surface of Y zeolite crystals. On the contrary, unsubstituted phthalocyanines are encapsulated in the supercages. Nitro-substitution improves considerably the activity of the complexes, as shown by the catalytic oxidation of cyclohexane to cyclohexanol and cyclohexanone at 298 K and 0.1 MPa with tertiary butyl hydroperoxide as oxygen donor.
