Acids from fruits generate photoactive Fe-complexes, enhancing solar disinfection of water (SODIS): A systematic study of the novel " fruto-Fenton " process, effective over a wide pH range (4-9) .

César Pulgarin, Aline Laetitia Schaub, Stefanos Giannakis, Giulio Farinelli, Mona Kohantorabi

This study aimed to enhance solar disinfection (SODIS) by the photo-Fenton process, operated at natural pH, through the re-utilization of fruit wastes. For this purpose, pure organic acids present in fruits and alimentary wastes were tested and compared wi ...

Reactivity and biological activity of N,N,S-Schiff-base rhodium pentamethylcyclopentadienyl complexes

Paul Joseph Dyson, Lucinda Kate Batchelor

Neutral piano-stool complexes of the general formula [(eta(5)-C5Me5)Rh(L-OR)] (R = Me, 1; R = Et, 2; R = Pe(i), 3) have been prepared in alcohols (methanol, 1; ethanol, 2; isopropanol, 3) from the Schiff-base 5-methyl-4-{(pyridin-2-ylmethylene)amino}-4H-1, ...

Ligand and Metal Based Multielectron Redox Chemistry of Cobalt Supported by Tetradentate Schiff Bases

Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez

We have investigated the influence of bound cations on the reduction of cobalt complexes of redox active ligands and explored the reactivity of reduced species with CO2. The one electron reduction of [CoII(Rsalophen)] with alkali metals (M = Li, Na, K) lea ...

Neutral chiral cyclopentadienyl Ru(II)Cl catalysts enable enantioselective [2+2]-cycloadditions

Nicolai Cramer, David Kossler

Cyclopentadienyl ruthenium(II) complexes with a large number of available coordination sites are frequently used catalysts for a broad range of transformations. To be able to render these transformations enantioselective, we have designed a chiral neutral ...

A Functional Model of [Fe]-Hydrogenase

Rosario Scopelliti, Xile Hu, Matthew Wodrich, Tao Xu, Simona Mazza

[Fe]-Hydrogenase catalyzes the hydrogenation of a biological substrate via the heterolytic splitting of molecular hydrogen. While many synthetic models of [Fe]-hydrogenase have been prepared, none yet are capable of activating H-2 on their own. Here, we re ...

Regioselective Nitration and/or Halogenation of Iridabenzofurans through Electrophilic Substitution

Andrew Francis Dalebrook

Regioselective electrophilic substitution reactions of the iridabenzofurans [Ir(C7H5O{OMe-7})(CO)(PPh3)(2)]-[OTf] (1) and IrCl(C7H5O{OMe-7})(PPh3)(2) (2) provide a convenient route to mononitro-, dinitro-, and mixed nitro-/halo- substituted derivatives. Tr ...

Characterization of high-spin metal-carbonyls in metal-organic frameworks with exposed cation sites

Wendy Lee Queen

The metal-org. frameworks M2(dobdc) (dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate, MOF-74, CPO-27) (M = Mg, Mn, Fe, Co, Ni, Zn) have shown considerable promise for a no. of gas storage and sepn. applications. These have included CO2/N2, CO2/H2, O2/N2, an ...

Reversible CO Binding Enables Tunable CO/H2 and CO/N2 Separations in Metal-Organic Frameworks with Exposed Divalent Metal Cations

Berend Smit, Wendy Lee Queen

Six metal-org. frameworks of the M2(dobdc) (M = Mg, Mn, Fe, Co, Ni, Zn; dobdc4- = 2,5-dioxido-1,4-benzenedicarboxylate) structure type bind carbon monoxide reversibly and at high capacity. IR spectra indicate that, upon coordination of CO to the divalent m ...

The Ligand-Based Quintuple Bond-Shortening Concept and Some of Its Limitations

Tobias Bauer

Herein, the ligand-based concept of shortening quintuple bonds and some of its limitations are reported. In dichromium-diguanidinato complexes, the length of the quintuple bond can be influenced by the substituent at the central carbon atom of the used lig ...
