Palladium alginate polymer beads for transfer hydrogenation of ketones |
| 초록 |
Transfer hydrogenation reaction is an alternative and greener approach to reduce the unsaturated bond. Herein, a novel functionalized alginate with palladium bead was developed cooperatively covered with polyethylenimine (PEI) and modified with CaCO3 composites as a catalyst. The advantage of heterogenized Pd alginate beads are very effective and reusability. The prepared polymer composites were characterized by various sophisticated techniques. Significantly, the TEM-EDS analysis showed that the weight % of Pd was found to be 0.6 % in the composite. The FTIR analysis confirmed the presence of functional groups in the alginate composites. The synthesized Pd alginate beads were used for the transfer hydrogenation of ketones to their corresponding alcohols and achieved good conversion (85-97%) with high selectivity. The catalyst was easily separated and reused for 5 times without loss of catalytic activity. The isolated catalytic products were characterized using 1H and 13C NMR studies. |
