Iron(III)‐porphyrin Complex FeTSPP: A Versatile Water‐soluble Catalyst for Oxidations in Organic Syntheses, Biorenewables Degradation and Environmental Applications

Abstract

The metal complex FeTSPP (5,10,15,20‐tetrakis‐(4‐sulfonato‐phenyl)‐porphyrin‐iron(III) chloride; also denoted as FeTPPS), which consists of an iron(III) center ion (an environmentally advantageous metal) and a highly water‐soluble heme ligand, represents an exciting and already broadly applied catalyst in the area of “green” oxidation reactions in aqueous media. This commercially available iron catalyst shows a high oxidation potential for many substrates. Further advantages are its high stability and ability not to aggregate in aqueous solution. This Minireview gives an overview of the structural properties of FeTSPP in aqueous solution and selected applications as an oxidation catalyst for organic syntheses, biorenewable degradations, and environmental applications.

Iron(III) porphyrin supported on S and N co-doped graphene quantum dot as an efficient photocatalyst for aerobic oxidation of alcohols under visible light irradiation

“…Metalloporphyrins as the well-known biomimetic photocatalysts using successfully as models for the cytochrome P-450 enzyme [20], have been widely investigated in variety of oxidation reactions [21][22][23][24]. Additionally, the metalloporphyrin derivatives, owning to their large πelectron systems leading to high absorption in visible light region [16,25], were used as a dye sensitizer in the photocatalysis processes.…”

Diazo ester insertion in NH bonds of amino acid derivatives and insulin catalyzed by water-soluble iron and ruthenium porphyrin complexes (FeTSPPCl) as application of carbenoid transfer in aqueous media

“…Aviv and Gross [18] also reported intermolecular N H insertion of anilines in water/THF catalyzed by myoglobin. Although, there are many examples showing that 5,10,15,20-tetrakis-(4-sulfonato-phenyl)-porphyrin-iron(III) chloride is a versatile water-soluble catalyst for oxidations in organic syntheses [22] and few other reactions [23,24], its use for carbenoid transfer in water seems to be neglected [25]. Comparative evaluation of reactivity for N-H insertion of different diazo derivatives with iron and ruthenium porphyrins will also be described.…”

Consecutive Oxidation/Condensation/Cyclization/Aromatization Sequences Catalyzed by Nanostructured Iron(III)‐Porphyrin Complex towards Benzoxazole Derivatives

“…More importantly, these catalysts can perform the oxidation of substrates, as well. [43] Initially, the nanostructured iron(III)-porphyrin was synthesized according to the literature with slight modification. [44,45] In a typical procedure, benzaldehyde and pyrrole were magnetically stirred in CH 2 Cl 2 in the presence of CF 3 SO 2 Cl at room temperature under nitrogen atmosphere to produce tetraphenylporphyrin.…”
