    Notes: Cobalt Chelate Complexes as Hydrogenation Catalysts. The Reduction of Nitro Compounds to Amines with Carbon Monoxid and Water as Hydrogenation AgentCobalt complexes of tetradentate chelating agents have been found to catalyse the selective homogeneous reduction of nitroaryls to amines with carbon monoxide and water at room temperature and atmospheric pressure. The cobalt complexes are highly specific. Dinitroaromatics can be reduced to the intermediate nitro amines in good yields; mixtures of nitroaryls can be reduced likewise sequentially. The reaction rate depends on the pH of the reaction solutions.

    The Cu Kα1,2 spectrum as measured with a curved-crystal spectrometer (1982)
    New York, NY [u.a.] : Wiley-Blackwell
    X-Ray Spectrometry 11 (1982), S. 149-152 
    Details

    Notes: An experimental study of the fine structure of the electron excited Cu Kα1,2 doublet in the energy range 20-40 ke V is presented. The spectra are different from earlier published ones in the sense that both the intensity and the resolution are high. A convex-crystal setting of the spectrometer is discussed. It is pointed out that when using a point source in association with a convex crystal the broadening due to the curvature of the planes vanishes. The high intensity enables one to unambigiously introduce two Lorentzians. The characteristic profile and location of the difference between the experimental data points and the fits show that the asymmetry of the Cu Ka1 and Kα2 lines most probably is due to the radiative Auger mechanism K-LM.
