This study investigates the oxidative transformation of diethylenetriaminepentaacetate (DTPA). a synthetic ligand. during drinking water ozonation. The rate coefficients for the reactions of CaDTPA(3-) and ZnDTPA(3-) with ozone were determined to be 6200 a ...
Norbornene and norbornadiene insert across the exo-face of their C=C bond into the Pd-acyl bond of [(OC)(3)Fe{mu-Si(OMe)(2)(OMe)}(mu-dppm)Pd{C(=O)Me}] and (1a) (dppm = Ph2PCH2PPh2) to afford the heterodinuclear complexes [(OC)(3){(MeO)(3)Si}Fe(mu-dppm)Pd{C ...
Iron regulatory proteins (IRPs)-1 and -2 bind specific mRNA hairpin structures known as iron-responsive elements and thereby post-transcriptionally regulate proteins involved in iron uptake, storage, and utilization. In this study, we compared modulation o ...
An organometallic transition state analog for the asym. redn. of acetophenone with a Cp*Rh complex was synthesized and structurally characterized - rac-[(C5Me5)RhOP(O)MePh] (3). This complex has a chiral N,N'-chelate ligand ...
A subpopulation of familial cases of amyotrophic lateral sclerosis has been linked to mutations in the gene encoding Cu/Zn superoxide dismutase (SOD1). There is in vitro evidence that certain SOD1 mutants, in addition to their normal dismutation function, ...
The binding of metal ions to self-assembled nitrilotriacetic acid (NTA)-modified thioalkane monolayers was monitored by impedance spectroscopy via a capacitance change of the blocking gold electrode. Binding to a fluorescent NTA-derivative and the native N ...
A photosensitizer complex of formulae (Ia) MX3Lt or (Ib) MXYLt in which M is a transition metal selected from ruthenium, osmium, iron, rhenium and technetium, preferably ruthenium or osmium; each X is a co-ligand independently selected from NCS,Cl,Br,I,CN, ...
In this paper, we present case studies of oxidative transformations of contaminants by oxidants which are relevant in natural and in technical systems. These oxidants are reactive oxygen species (ROS), manganese(III,IV), iron(III), and molecular dioxygen ( ...
Solutions of the strong complexing agent ethylenediaminetetraacetic acid (EDTA) and Cu, Pb, Cd, Al, and Fe(III) were examined by electrospray mass spectrometry (ES/MS). Uncomplexed EDTA and metal-EDTA complexes survive the electrospray process intact and c ...
The reversible oriented immobilization of proteins on solid surfaces is a prerequisite for the investigation of mol. interactions at interfaces or the construction of supramol. assemblies. We demonstrate a generally applicable method using a synthetic chel ...
