Dx. Jiang et al., Sterically hindered iron-porphyrins as catalysts in cyclohexane oxidation.Steric effect of oxygen transfer from PhIO to iron(III)-porphyrins, J CHEM R-S, (1), 2001, pp. 24-25
Six sterically hindered chloro meso-tetra-ortho-alkylphenylporphinato iron
complexes (T(o-R)PPFe(III)Cl, R=Me, Et, n-Pr, n-Bu, i-Pr, t-Bu) were used t
o catalyse the monooxygenation of cyclohexane with PhlO. A special steric e
ffect of these alkyl substituents R on the catalytic character is proposed
on the basis of the results.
