TL;DR: In this article, a supramolecular species [MnTPyP{Ru(bipy) 2 H 2 O} 4 ](PF 6 ) 9 containing four cis-bis(Bipyridine)(aqua)ruthenium(II) complexes attached to the peripheral pyridyl groups of meso-tetra(4-pyridym)porphyrin manganese(III) (Mn TPyP) has been synthesized, and employed as the precursor of a rather promising multinuclear ox
Journal ArticleDOI
Biomimetic metal-oxidant adducts as active oxidants in oxidation reactions
TL;DR: In this paper, the authors focus on the synthesis, characterization, and reactivity studies of metal-oxidant adducts, such as metal-iodosylarene, -hydro(alkyl)peroxo, -acylperoxideo, and -hypochlorite complexes, in heme and nonheme systems.

Local Structure of Nitrogen Atoms in a Porphine Ring of meso-Phenyl Substituted Porphyrin with an Electron-Withdrawing Group Using X-ray Photoelectron Spectroscopy and X-ray Absorption Spectroscopy
TL;DR: This study investigated the protonation of nitrogen atoms in porphyrins with meso-phenyl p-substituted by an electron-withdrawing group using N 1s X-ray photoelectron spectroscopy, the N K X-Ray absorption near-edge structure (XANES), and the discrete variational (DV)-Xalpha molecular orbital (MO) method.

Synthesis of poly(ethylene glycol)-supported manganese porphyrins: efficient, recoverable and recyclable catalysts for epoxidation of alkenes.
TL;DR: Two new poly(ethylene glycol) supported manganese porphyrins have been prepared and their catalytic activity and recyclability were investigated for the epoxidation of alkenes using H2O2 and PhIO as stoichiometric oxidants.
