| Abstract Scope |
Two new isostructural inorganic coordination polymers, [M(C14H8O6)(C10H8N2)2H2O)]·(C3H7NO), (M=Co, Ni) were prepared employing 2, 5-bis(prop-2-yn-1-yloxy)terephthalic acid and 4,4´ bipyridine as ligands. The connectivity between the metal-centers and the ligands give rise to a two-dimensional layer structure, which are stacked one over the other in ABABAB··· fashion. The Co-containing compound, 1, carbonized directly to produce Co-nanoparticles, supported over highly porous carbon. The Co@C–T compounds were found to be active for the Bechamp reaction of reduction of nitroarenes to aminoarenes under solvent-free conditions. The Ni-containing compound, 2, was loaded with Pd-nanoparticles by known procedures. The Pd@2 sample found to be a good catalyst for the Suzuki-Miyaura C–C coupling of chloroarenes in ethanol at 75 °C. The present work demonstrates clean and green approach for the preparation of new heterogeneous catalysts for the reduction of nitroarenes under solvent-free conditions and especially towards activating chloro-arenes under recyclable reaction conditions employing environmentally benign ethanol. |
