    Complexes of Bidentate Phosphane Selenide Ligands with Mesitylenetellurenyl Iodide and with Tellurium Diiodide,

    EUROPEAN JOURNAL OF INORGANIC CHEMISTRY, Issue 6 2006
    Cristian G. Hrib
    Abstract Bis(diphenylphosphanyl)methane diselenide (dppmSe2, 1) and bis(diphenylphosphanyl)ethane diselenide (dppeSe2, 2) reacted with 2 equiv. Br2 or I2 to form the insoluble solid products, dppm(SeX2)2 (X = Br, 3; X = I, 4) and dppe(SeX2)2 (X = Br, 5; X = I, 6). However, using the iodine-like electrophile mesitylenetellurenyl iodide (MesTeI, 7), fairly soluble complexes, dppmSe2[Te(I)Mes]2 (8) and dppeSe2[Te(I)Mes]2 (9), were obtained. Complexes 8 and 9 contain two T-shaped (10-Te-3) Se,Te(Mes),I moieties bridged by dppm or dppe; solid 9 exhibits intermolecular soft,soft interactions between approximately linear Se,Te,I units. In a side reaction accompanying the crystallisation of complex 8, or by the reaction of 1 with Te and I2, a chelate complex dppmSe2TeI2 (10) was formed. Fortuitously, a crystal of the related compound dppeSe2TeI2 (11) was also obtained. In 10, a square planar cis -Se2TeI2 group is part of a six-membered ring, and 11 is a coordination polymer with trans -Se2TeI2 moieties bridged by dppe. Averaged 31P- and 77Se NMR signals including 77Se,31P couplings, together with broad 125Te NMR singlets indicate phosphane selenide ligand exchange in solution, that is, the kinetically labile behaviour of complexes 8 and 9.

    Selective Oxidation of Aromatic Amines to Nitro Derivatives using Potassium Iodide- tert -Butyl Hydroperoxide Catalytic System

    ADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 1-2 2009
    K. Rajender Reddy
    Abstract The direct oxidation of aromatic primary amines to the corresponding nitro compounds selectively in 47,98% yields has been achieved by using potassium iodide as catalyst and tert -butyl hydroperoxide as the external oxidant. The present catalytic system works well for both electron-rich and electron-poor substrates. [source]


    Quantum Yield of the Iodide,Iodate Chemical Actinometer: Dependence on Wavelength and Concentration,

    PHOTOCHEMISTRY & PHOTOBIOLOGY, Issue 2 2003
    Ronald O. Rahn
    ABSTRACT The quantum yield (QY) of the iodide,iodate chemical actinometer (0.6 M KI,0.1 M KIO3) was determined for irradiation between 214 and 330 nm. The photoproduct, triiodide, was determined from the increase in absorbance at 352 nm, which together with a concomitant measurement of the UV fluence enabled the QY to be calculated. The QY at 254 nm was determined to be 0.73 ± 0.02 when calibration was carried out against a National Institute of Standards and Technology traceable radiometer or photometric device. At wavelengths below 254 nm the QY increased slightly, leveling off at ,0.80 ± 0.05, whereas above 254 nm the QY decreases linearly with wavelength, reaching a value of 0.30 at 284 nm. In addition, the QY was measured at different iodide concentrations. There is a slight decrease in QY going from 0.6 to 0.15 M KI, whereas below 0.15 M KI the QY drops off sharply, decreasing to 0.23 by 0.006 M KI. Calibration of the QY was also done using potassium ferrioxalate actinometry to measure the irradiance. These results showed a 20% reduction in QY between 240 and 280 nm as compared with radiometry. This discrepancy suggests that the QY of the ferrioxalate actinometer in this region of the spectrum needs reexamination. [source]

    Metal-free MIRAS phasing: structure of apo-S100A3

    ACTA CRYSTALLOGRAPHICA SECTION D, Issue 8 2002
    Peer R. E. Mittl
    S100 proteins are involved in metal-dependent intracellular signalling. Metal-free S100A3, a cysteine-rich Ca2+ - and Zn2+ -­binding protein, has been crystallized by vapour diffusion under the strict exclusion of oxygen and in the absence of divalent metal ions. Metal binding induces large conformational changes, rendering the apo-S100A3 crystals very sensitive to various metal compounds. Therefore, the structure was solved by MIRAS phasing using potassium iodide and xenon derivatives. Iodide replaces a water molecule at the surface of the S100A3 protein, whereas xenon binds in a hydrophobic cavity at the dimer interface. Despite significant non-isomorphism, the combination of both derivatives was sufficient for structure determination. The overall apo-S100A3 structure resembles the structures of metal-free S100B and S100A6 solution structures. In contrast to the NMR structures, the EF-hand loops are well ordered in the apo-S100A3 crystal structure. In the N-terminal pseudo-EF-­hand loop a water molecule occupies the position of the Ca2+ ion. The C-terminal canonical EF-hand loop shows an extended conformation and a different helix arrangement to other S100/metal complex crystal structures. [source]

    4414: Flow cytometry for the characterization of retinal neural populations and the quantification of retinal apoptosis

    ACTA OPHTHALMOLOGICA, Issue 2010
    PA TSOKA
    Purpose The primary purpose of this study was to evaluate the potential to quantify the different retinal neuronal populations, as also the retinal detachment-induced apoptosis in Sprague,Dawley rats, in an accurate quantitative way by using flow cytometry. Methods Retinal detachment was performed on the right eye of deeply anesthetized animals. The detachment was induced by a sub-retinal injection of sodium hyaluronate. Rats were sacrifised and the eyes were enuclated to achieve retinal dissection. Tissue dissociation was accomplished with trypsin. The cells were mechanically dissociated into a single-cell suspension. At least 100.000 cells were analyzed with a FACScalibur and FlowJo software. The primary antibodies were anti-rhodopsin against rod photoreceptors, anti-PKC against rod bipolars, anti-calbindin against horizontals, anti-ChAT against cholinergic amacrine cells and anti-MAP1 against ganglion cells. Annexin-V-FITC/Propidium Iodide was used to identify apoptosis. Results Quantification of retinal neuronal cells was possible using flow cytometry. Photoreceptors had the 53.99%, the ganglion the 7%, the bipolars the 2%, the horizontal the 4% and the cholinergic amacrine cells the 1,5% in the hole mixed retinal population. Quantification of the apoptotic rate was also possible. The early apoptotic cells was 22.4% while in the control eye was 6.28% after retinal detachment. The experiments were repeated ten times and these measurements are the mean value. Conclusion Flow cytometry can be used to quantify the apoptotic neuronal cells as well as the healthy retinal neurons. It is quick and precise and it will be very useful in future in studies in neuroprotection and quantification of apoptosis during time. [source]
