Abstract
Heme enzymes are capable of catalytically oxidising organic substrates using peroxide via the formation of a high-valent intermediate. Iron porphyrins with three different axial ligands are created on self-assembled monolayer-modified gold electrodes, which can oxidize C-H bonds and epoxidize alkenes efficiently. The kinetic isotope effects suggest that the hydrogen atom transfer reaction by a highly reactive oxidant is likely to be the rate-determining step. Effect of different axial ligands and different secondary structures of the iron porphyrin confirms that the thiolate axial ligand with a hydrophobic distal pocket is the most efficient for this oxidation chemistry.

Abstract
Porphyrins and metalloporphyrins provide an extremely versatile nanometer-sized building block for the control of materials properties. Films, solids and microporous solids have been explored as field-responsive materials (i.e. interactions with applied electric, magnetic or electromagnetic fields) and as ‘chemo-responsive’ materials (i.e. interactions with other chemical species as sensors or for selective binding or catalysis).

Abstract
The synthesis of 2, 3, 7, 8, 12, 13, 17, 18-octabromo-meso-tetrakis(2-pyridyl)porphyrin, H 2 Br 8 T 2 PyP , is described, including the comparison of four attempted methods for the demetallation of ZnBr 8 T 2 PyP . One of the methods represents a strategy of demetallation based on the acid-base properties of the macrocycle, the solvent-dependent kinetics of metal insertion into porphyrins and the pH -dependent solubility of the 2-pyridylporphyrin derivatives in water. Self-coordinating aggregation of ZnBr 8 T 2 PyP in non-coordinating solvents was verified by 1 H NMR spectroscopy. The Mn(III)/Mn(II) redox potential for MnBr 8 T 2 PyPCl is 0.38 V higher than the reduction potential measured for its first-generation analogue, MnT 2 PyPCl . Cyclohexane hydroxylation by iodosylbenzene was performed in CH3 CN catalyzed by MnBr 8 T 2 PyPCl and MnT 2 PyPCl . MnBr 8 T 2 PyPCl was highly active, even at low concentration (5 × 10−5 M ), but perhalogenation did not account for oxidative robustness. At such a low catalyst concentration, MnT 2 PyPCl exhibited no activity as inferred by comparison to blank experiments.

Abstract
In the present publication we report on the preparation and spectroscopic features of a penta-coordinate rhodium(III) complex of corrole with bulky ortho-phenyl substituents at the meso positions, Rh ( tdcc )( PPh 3)[ tdcc = tris (2,6- dichlorophenyl ) corrole ]. Addition of pyridine to Rh ( tdcc )( PPh 3), as well as to the closely related complex of tris(pentafluorophenyl)corrole [ Rh ( tpfc )( PPh 3)] reported earlier, leads to hexa-coordinated rhodium complexes with pyridine and PPh 3 occupying the axial positions. The structures of these two compounds were investigated by NMR and X-ray crystallography. The catalytic potency of Rh ( tdcc )( PPh 3) was found significantly lower than that of Rh ( tpfc )( PPh 3), which suggests that excess steric crowding prevents efficient carbene-transfer catalysis.

Abstract
Two new models for cytochrome P450 in which the thiolate axial ligand is replaced by a RSO(3)(-) group, form oxo-iron(IV) porphyrin pi-cation radicals as sole oxidation products in "peroxo shunt" reactions independent of the nature of the employed solvent (polar or non-polar) and electronic nature of the porphyrin rings. Although the properties of the solvent and push-pull effects from the porphyrin rings do not affect the mode of the O-O bond cleavage (heterolytic or homolytic) in these models, they strongly affect the rate and mechanism of each reaction step leading to the formation of the high-valent iron intermediates. This article reports the results of mechanistic studies involving the measurements of the rate of oxo-iron(IV) porphyrin pi-cation radical formation from the enzyme mimics of P450 for different oxidant concentration, temperature and pressure in selected organic solvents. Extraction of the appropriate rate constants and activation parameters for the reactions studied enable a detailed discussion of the effects of solvent and electronic nature of the porphyrin rings on the position of the first pre-equilibrium involving formation of the acylperoxo-iron(III) porphyrin intermediate, as well as on the rate of heterolytic O-O bond cleavage leading to the formation of the high-valent iron species. Furthermore, an unusual effect of solvent on the kinetics of oxo-iron(IV) porphyrin pi-cation radical formation in methanol is demonstrated and discussed in the present work.

Abstract
On pyrrole! The pyrrole-based corrole ligands can offer an alternative to porphyrin systems. The manganese corroles 1-4 are readily synthesized, undergo metal- not ligand-based redox chemistry, and 4 in particular shows impressive catalytic activity in the oxygenation of styrene with iodosylbenzene.

Abstract
A chemical model system for cytochrome P450, a porphyrin and an oxidant, was used in Ames assay as a substitute for S9 mix. In the presence of tetrakis(pentafluorophenyl)porphyrinatoiron(III) chloride [Fe(F5P)Cl] and tert-butyl hydroperoxide (t-BuOOH), mutagenicity of N-nitrosodibutylamine (NDB) in Salmonella typhimurium TA1535 was detected. The mutagenicity depended on the pre-incubation period, and also on the concentration of an oxidant and of bacteria. In the chemical model system, pH affected the mutagenicity of NDB, which suggested that as observed in an enzymatic activating system, the mutagenicity was due to the labile alkylating species which was derived from NDB activated in the chemical activation system and was sensitive to pH. Under the optimum conditions; a higher concentration of an oxidant, a higher concentration of bacterial culture, and a weakly acidic medium, mutagenicity of N-nitrosodipropylamine in S. typhimurium TA1535 was also detected. Besides N-nitrosodialkylamines, 2-aminofluorene (2-AF) and benzo[a]pyrene (BaP) were also used as mutagens. Mutagenicity of 2-AF and BaP in S. typhimurium TA1538 were both detected in the same system as used in detecting the mutagenicity of N-nitrosodialkylamines. Ames test using a metalloporphyrin/oxidant model system makes it possible to detect mutagenicity derived from both base pair substitution mutagens and frameshift mutagens without using enzymatic activating system. These results demonstrate that the assay with the chemical model system is useful in detecting unstable unknown active mutagens or investigating the mechanisms of the metabolic pathway of mutagens or carcinogens in a protein-free medium.
