The preparation of new palladium (II) complexes with Schiff base type ligands and its impregnated Al2O3 materials: As the catalysts for degradation/reduction of organic dyes

The removal of organic dyes used in many sectors such as textile, paper, leather, and packaging from water sources is very important in terms of preventing the spread of industrial pollutants to the environment. Transition metal complexes supported to an inorganic solid material are frequently used for the degradation/reduction of organic dyes causing this pollution. In this study, new Pd (II) complexes with Schiff base ligands were synthesized and structurally characterized by nuclear magnetic resonance (NMR), Fourier-transform infrared spectroscopy (FT-IR), mass spectrometry (MS), and single-crystal X-ray diffraction (sc-XRD) spectroscopic methods. Then, the Al2O3-impregnated materials of these Pd (II) complexes were prepared and characterized by scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX), FT-IR, and thermogravimetry (TG) techniques. The catalytic activities of the synthesized Pd (II) complexes and their Al2O3-impregnated materials were comparatively analyzed to investigate the degradation/reduction of organic dyes (2-nitroaniline, 4-nitroaniline, 4-nitrophenol, eosin yellow, and methylene blue). The catalytic results indicate that Al2O3-impregnated materials are very active catalysts for the degradation/reduction of organic dyes under those circumstances. Conversions of up to 98% for all substrates were obtained after 5 min at ambient temperature.

Studies on the Conformation of 5,15-Diarylporphyrins with (Arylsulfonyl)oxy Substituents

Dimeso-substituted octaalkylporphyrins, carrying an (arylsulfonyl)oxy group at the ortho position of the two (meso) phenyl groups, were synthesized from dipyrrolylmethanes and aldehydes.On account of a 1H NMR upfield shift in CDCl3 solution of 2-5 ppm for the aryl protons, a folded conformation is assumed in which the substituted aryl groups lie right above and below the porphyrin plane.In CDCl3/CF3COOH solution the upfield shifts are absent.The results of low-temperature 1H NMR measurements and ring-current calculations agreed with our assumptions.The sulfonyloxy group promotes folding of the molecule more than the ester, sulfonyl, sulfinyl, thio, or methylene group.In zinc porphyrins carrying anthraquinone substituents, intramolecular coordination was observed. ΔG, ΔH, and ΔS values for the various conformational equilibria were calculated from the NMR data.We suggest van der Waals interactions with a contribution of charge transfer as the driving force for the folding of the molecule.
