IIITPP, however, is shown by experiments with with 5,10-dipyridyl and 5,10,15,20-tetrapyridyl analogues of the tetraphenylporphyrin catalyst.

Included as Supporting Information are extended TON versus time plots for all additives examined. Consistent with Figure 1, those showing TON amplification after 5 min showed additional amplification at longer times.

Presumably the oxo-bridged iron dimer is thermodynamically more stable with respect to dissociation into monometallic components, via oxygen atom transfer, than is the manganese porphyrin dimer. While the doubly bridged salen compound may be similarly stabilized, such stability is probably less relevant, since loss of salen catalytic activity appears to be due mainly to irreversible ligand oxidation.

More rapid cycling through B will also diminish the rate of anthracene consumption via cycle A. An additional factor, however, may be an ability of the most reactive substrates to react also with the dimer (albeit slowly), thus supplanting to some extent the role of anthracene as catalyst regenerator.

Consistent with this suggestion, pyridine addition to a deactivated porphyrin catalyst is observed to restore activity for styrene epoxidation, although less efficaciously than anthracene addition. Accompanying the restored catalytic activity is pyridine N-oxide formation. Addition of the N-oxide to a deactivated catalyst, on the other hand, has no restorative effect.

Collman and co-workers (Inorg. Chem., 2000, 39, 4625-4629) have presented evidence for another interesting role for pyridine. They find that conversion of pyridine to pyridine N-oxide renders the ligand a better donor to manganese, thereby enhancing its catalytic activity.
