Use of chemical kinetics for the description of metal porphyrin reactivity

The results of use of chemical kinetics receptions, approaches and methods for the study of porphyrins and their metal complexes reactivity are discussed on an example of oxidation, acid-basic, and catalytic reactions of rhodium, palladium, and rhenium complexes of porphyrin in liquid solutions. The peculiarity of the porphyrin reaction rates is analyzed in a brief context of general provisions of the chemical kinetics. The opportunity to use the quasistationarity principle at the definition of the kinetic equation of the reactions with participation of metal porphyrins is shown. The transition from the process kinetic description to consideration of its mechanism is explored.

Effects of p-substituents on electrochemical CO oxidation by Rh porphyrin-based catalysts

Electrochemical CO oxidation by several carbon-supported rhodium tetraphenylporphyrins with systematically varied meso-substituents was investigated. A quantitative analysis revealed that the p-substituents on the meso-phenyl groups significantly affected CO oxidation activity. The electrocatalytic reaction was characterized in detail based on the spectroscopic and X-ray structural results as well as electrochemical analyses. The difference in the activity among Rh pophyrins is discussed in terms of the properties of p-substituents along with a proposed reaction mechanism. Rhodium tetrakis(4-carboxyphenyl)porphyrin (Rh(TCPP)), which exhibited the highest activity among the porphyrins tested, oxidized CO at a high rate at much lower potentials (2 oxidation activity, in contrast to Pt-based catalysts.

A facile synthesis of rhodium(III) porphyrin-silyls

Rhodium(III) porphyrin-silyls [Me3SiRhT(p-X)PP (X=H, Me)] were synthesized from the reactions of the rhodium(I) porphyrin anions, generated from the reduction of the rhodium(III) porphyrin chlorides with the sodium amalgam in toluene, with degassed Me3SiCl at room temperature. A single crystal structure of (5,10,15,20-tetraphenylporphyrinato)(trimethylsilyl)rhodium(III) (1) showed that the Rh-Si bond length is equal to 2.305 ?.
