  Coordination of 5,10,15,20-tetraphenyl-21H,23H-porphin by rhenium in various oxidation states

  摘要：

  A method was developed for the synthesis of three rhenium complexes, (5,10,15,20-tetraphenyl-21H,23H-porphinato)(phenoxo)rhenium(III) (PhO)ReTPP, (5,10,15,20-tetraphenyl-21H,23H-porphi-nato)(chloro)rhenium(III) (Cl)ReTPP, and mu-oxo-bis[(oxo)-(5,10,15,20-tetraphenyl-21H,23H-porphi-nato)rhenium(V)] [O=ReTPP](2)O, by one reaction between porphyrin H2TPP and H2ReCl6 in boiling phenol. In the complex formation reaction accompanied by the redox process, only the metal cation is involved in the transformation. Rhenium(IV) as chlororhenic acid dispropoportionates without participation of solvent or porphyrin to give Re(III) and Re(V) complexes. The chemical structures of the products were established by spectral and elemental analysis. Characteristics of the UV, Vis, IR, and H-1 NMR spectra, the chromatographic mobility, and stability of the complexes were determined.

  Chemical structure and reactions of axially coordinated iridium(III) porphyrins

  摘要：

  Effect of modification of the axial (fifth and sixth) coordination sites on the physicochemical properties and reactivity of iridium(III) complexes with 5,10,15,20-tetraphenyl-21H,23H-porphine was studied. Oxidation reactions of (Cl)(H2O)IrTPP in protic solvents by atmospheric oxygen (on assistance of protons at high concentration) preceded by ligand substitution at the axial position were studied. It was found that (Cl)(H2O)IrTPP in 100% AcOH undergoes slow one-electron oxidation at the aromatic ligand to form pi cation radical (CH3COO)(CH3COOH)IrTPP center dot+. The reaction was studied in 100% AcOH (H2O content 0.078%) at 288-308 K, its kinetic parameters were obtained. The (Cl)(H2O)IrTPP reaction product in CF3COOH was identified as complex (CF3COO)(2)(IrTPP)-T-IV oxidized at the central metal cation. It was experimentally confirmed that the reaction in 99% CF3COOH at 298 K proceeds in two stages: the substitution of axial Cl- and H2O by excess CF3COO- (k (eff) = (1.8 +/- 0.1) x 10(-3) s(-1)) and the oxidation of iridium to Ir(IV) (k (eff) = (8.0 +/- 0.5) x 10(-5) s(-1)). Data on similar Re(III) complexes (PhO)ReTPP and (Cl)ReTPP are presented for comparison.
