Five new iron polyfluorinated porphyrin complexes have been prepared by selective substitution of the para-F atoms of iron m&so-tetra(pentafluorophenyl)porphyrin [Fe(TF5PP)Cl] with NEt2, NHPr, OPh, SBu and SO2Bu groups. They all exhibit a redox potential for the Fe(III)-Fe(II) couple around -0.1 V (vs SCE); the complex bearing para-SO2Bu groups shows a redox potential positively shifted by about 100 mV. The iron complexes in which the para-F atoms of Fe(TF5PP)Cl are replaced with NR2 or SR groups were much less active catalysts in heptane hydroxylation by PhIO than Fe(TF5PP)Cl, while those bearing OPh and SO2Bu para-substituents are as efficient catalysts as Fe(TF5PP)Cl. The Fe(TF4SO2BuPP)Cl complex appears to be the most appropriate catalyst for alkane hydroxylation in the presence of more reactive substrates such as alkenes, as shown by experiments performed on cyclooctene-heptane mixtures.
