Axial ligand exchange of iron(III) tetramesitylporphyrin phenolate complexes

The axial ligand of a series of iron(III) 5,10,15,20-tetramesitylporphyrin phenolate complexes was found to exchange with added carboxylic acids and alcohols. The rates of axial ligand exchange with carboxylic acids were found to be dependent on acidity of the carboxylic acid, basicity of the phenolate, and the steric bulk of both the carboxylic acid and the phenolate axial ligand. The rates of axial ligand exchange with alcohols were found to be dependent on the nucleophilicity of the alcohol, leaving group ability of the phenolate, and the steric bulk of both the alcohol and the phenolate axial ligand. Different mechanisms for ligand exchange are proposed for carboxylic acids and alcohols. The Royal Society of Chemistry 1999.

Acylperoxo-iron(III) porphyrin complexes: A new entry of potent oxidants for the alkene epoxidation

Competitive epoxidation of norbomylene and α-methylstyrene by peracids in the presence of iron porphyrins has been carried out in methylene chloride and toluene at -78 °C. When (TMP)FeIII(RCO2) (TMP = 5, 10, 15, 20-tetramesitylporphyrin) is used as a catalyst in methylene chloride, selectivity of norbomylene oxide over α-methylstyrene oxide is almost identical even though a variety of peracids are used, since O=FeIVTMP π-cation radical 2a is the common oxidant in the reactions. On the other hand, the selectivity in the epoxidations catalyzed by (TDCPP)FeIII(X) (TDCPP: 5, 10, 15, 20-tetrakis(2,6-dichlorophenyl)porphyrin) is found to be dependent on the structure of peracids. The latter type of the results is also obtained for the reactions catalyzed both by (TMP)FeIII(X) and by (TDCPP)FeIII(X) in toluene. The dependence of the selectivity in the epoxidation on the structure of peracids is attributed to the alteration of the oxidant from 2 to peracid-Fe(III) complexes 1. The direct involvement of 1 in the epoxidation has been further confirmed by spectroscopic studies of the reactions. Under the catalytic epoxidation conditions at low temperature, the participation of 1 and 2 as the active species is controlled either by electronic structure of iron porphyrin complexes (push-pull effect) or by alteration of the solvent.
