Abstract
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 to catalyse the monooxygenation of cyclohexane with PhIO. A special steric effect of these alkyl substituents R on the catalytic character is proposed on the basis of the results.
