TL;DR: In this article, the authors investigated the catalytic activity of representatives of the three generations of iron porphyrins, namely [5,10,15,20-tetraphenylporphyrin]iron(III) chloride (Fe(TPP)Cl), [5.10, 15, 20tetrakis(2,6-dichlorophenyl)porphynyl)

TL;DR: The catalytic activity of the whole set of complexes has been tested with regard to the epoxidation of aromatic alkenes with peracetic acid and, in the particular case of styrene, good selectivities and moderate enantioselectivities were obtained.

A novel strategy for clean and selective oxygenation of hydrocarbons with n-Bu4NHSO5 in neat water catalyzed by recyclable water-insoluble iron (III) tetraphenylporphyrins
TL;DR: In this paper, a novel heterogeneous method for efficient oxygenation of olefins to epoxides and saturated hydrocarbons to the related ketones using tetrabutylammonium peroxomonosulfate (n-Bu4NHSO5) in neat water catalyzed by Fe(TPP)Cl and Fe(TDCPP)Cl complexes as water-insoluble catalysts has been developed.

Three Generations of Cobalt Porphyrins as Catalysts in the Oxidation of Cycloalkanes
Katarzyna Pamin,Edyta Tabor,Sylwia Górecka,Władysław W. Kubiak,Dorota Rutkowska-Zbik,J. Połtowicz +5 more
TL;DR: Three generations of cobalt porphyrins were synthesized, physicochemically characterized by FTIR and UV/Vis spectroscopy as well as cyclic voltammetry and applied as catalysts in the oxidation of cycloalkanes with atmospheric molecular oxygen under mild conditions and a reaction mechanism is proposed and discussed.

Silica-bound imidazole as a heterogeneous axial ligand for Mn(salophen)Cl: Efficient, recoverable and recyclable catalyst for epoxidation of alkenes and hydroxylation of alkanes with sodium periodate
TL;DR: In this paper, the effect of reaction parameters such as solvent and oxidant in the epoxidation of cis-cyclooctene were investigated and the obtained results showed that this catalyst is a robust and stable heterogeneous catalyst and can be recovered quantitatively by simple filtration and reused without loss of its acivity.
