In Fig. 2, the plot of 4-substituted styrenes deviates from the linear correlation rather than that of 3-substituted styrenes. The deviation would be caused by the steric or electronic interaction between the substituents at the 4-position of styrenes and methoxymethyl moieties of the porphyrin

The major enantiomer of the cis-oxide had a (1S,2R)-configuration, which was derived from minor benzyl cation intermediate. The cis/trans ratio at the ring closure step should be different between the major pathway and the minor one, because the major and minor intermediates are diastereomers and therefore the lifetime and the steric circumstances between these intermediates would differ. There would be a tendency that the favored intermediate selectively affords the major diastereomer of the product, while the minor intermediate preferentially gives the minor diastereomer: W.

In iron porphyrin-catalyzed oxidation with iodosylarenes, a Ph-IO-ligated complex of the catalyst is proposed to be a major active oxidant in the presence of olefins. For the mechanism of the oxidation by metalloporphyrin with PhIO, see: J.P. Collman, A.S. Chien, T.A. Eberspacher, and J.I. Brauman J. Am. Chem. Soc. 122 2000 11098
