| Abstract: | The title complex was synthesized from PdCl2 and poly(acrylonitrile-vinyltri-ethoxysilicon) supported on fumed silica. The hydrogenation reaction of carbonyl group in aldehydes and ketones into methylene or methyl group was carried out with room temperature and 1 atm H2. The high conversion of aldehydes and ketones were observed. The datum of XPS, x-ray diffraction and E. M. analysis showed that the active center may be the complex compound composed of the nitrogen of acrylonitrile ligand and Pd atom in PdCl2 |
