Primidone oxidation catalyzed by metalloporphyrins and Jacobsen catalyst
(ELSEVIER SCIENCE BV, 2008)
Primidone (PRM) oxidation by various oxidants such as iodosylbenzene (PhIO), tert-butyl hydroperoxide 70wt.% (t-BOOH), 3-chloroperoxybenzoic acid (m-CPBA) and hydrogen peroxide 30wt.%, mediated by either a salen complex ...
HPLC-ESI-MS/MS analysis of oxidized di-caffeoylquinic acids generated by metalloporphyrin-catalyzed reactions
(Sociedade Brasileira de Química, 2008)
This paper reports an HPLC-ESI-MS/MS investigation on the oxidation of 3,5- and 4,5- dicaffeoylquinic acid using iron(III) tetraphenylporphyrin chloride as catalyst. Two major mono-oxidised products of the quinic acid ...
Metalloporphyrins as cytochrome P450 models for chlorhexidine metabolite prediction
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The catalytic oxidation of chlorhexidine (CHX, a strong microbicidal agent) mediated by ironporphyrins has been investigated by using hydrogen peroxide, mCPBA, tBuOOH, or NaOCl as oxidant. All of these oxygen donors yielded ...
Study of the catalytical intermediates of metalloporphyrins supported on imidazole propyl gel
(Elsevier B.V., 1997-03-14)
In this work, the catalytic intermediates for Fe(TPP)(+), Fe(TDCPP)(+), Fe(TFPP)(+), Mn(TPP)(+) and Mn(TDCPP)(+) supported on imidazole propyl gel with PhIO were studied by UV-Vis spectrophotometry. For Fe(TPP)+ and Fe(TFPP)+ ...

Supramolecular conformational effects in the electrocatalytic properties of electrostatic assembled films of meso(3-and 4-pyridyl) isomers of tetraruthenated porphyrins
(Soc Brasileira QuimicaSao PauloBrasil, 2005)
Immobilization of Fe, Mn and Co tetraphenylporphyrin complexes in MCM-41 and their catalytic activity in cyclohexene oxidation reaction by hydrogen peroxide
(2008)
Metalloporphyrin catalysts are able to carry out selective oxidation of organic substrates with several oxidizing agents. Recently, mesoporous materials have been studied as supports because they present high specific ...
Electrocatalytic reduction of nitrite on tetraruthenated metalloporphyrins/nafion glassy carbon modified electrode
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Organic-inorganic hybrid material containing porphyrin and metalloporphyrins using sol-gel process.
