Beschreibungen/Notizen

• The Pd II complex was synthesized on the platform of hyperbranched polyester polyphthalate. The polymeric ligand and complex were characterized by different methods, including 1 H NMR, IR spectroscopy, electron spectroscopy in the visible and UV ranges, elemental analysis, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), electron microscopy, nitrogen adsorption/desorption, temperature-programmed reduction (TPR) in a hydrogen flow, and XRD. The polymer macromolecule was found to contain ten terminal phthalate groups. The Pd II complex is characterized by the ratio ligand: Pd II = 2: 5 and contains a square-planar coordination site, which favors the formation of a cluster with the predominant pore diameter from 2 to 10 nm. After the reduction of the Pd II complex in a hydrogen flow, Pd 0 nanoparticles stabilized on the polymer substrate were obtained. The complex showed a high catalytic activity in the reduction of α-methylstyrene to cumene under mild conditions.
