Catalytic transfer hydrogenation of aromaticnitro and carbonyl compounds was carried out using novel cobalt(II) substituted hexagonal mesoporous aluminophosphate molecular sieves. The catalyst showed excellent yield with good recycling capability.
The present invention relates generally to compounds represented in Formula I, pharmaceutical compositions comprising them and methods of treating of diseases or disorders related to the function of the calcium sensing receptor. The invention also relates to processes for making such compounds and to intermediates useful in these processes.
Simple and Practical Synthesis of Various New Nickel Boride-Based Nanocomposites and their Applications for the Green and Expeditious Reduction of Nitroarenes to Arylamines under Wet-Solvent-Free Mechanochemical Grinding
paper, we report a simple synthesis of four new nickel boride-based nanocomposites, namely Ni2B@ZrCl4, Ni2B@Cu2O, Ni2B@CuCl2 and Ni2B@FeCl3, from commercially available and cheap starting materials. All of the new Ni2B-based nanocomposites were well characterized by Fourier-transform infraredspectroscopy, X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy.
