Catalytic and biological properties of palladium(II) complexes with bidentate Schiff base ligands

Abstract

In this study, we synthesized and characterized Schiff base ligands (S1–3), which contained sulfonamide/sulfonate groups, and their corresponding Pd(II) complexes (K1–3). We also introduced these complexes into Al2O3‐supported materials (M1–3) using the impregnation method. Following the structural characterization, we proceeded to evaluate the performance of the supported materials in a series of degradation and reduction reactions of involving organic pollutants. These assessments were conducted with the intention of exploring their potential as catalysts in aqueous environments in the presence of NaBH4. The study's findings present novel approaches to develop effective catalysts for reducing/degrading organic pollutants in aqueous environments. The M2 catalyst showed excellent results for dye mixing after 90 s. Additionally, we investigated the antibacterial and cytotoxic properties of the synthesized compounds. The outcome also suggests that these synthesized compounds exhibit potential antibacterial and cytotoxic properties.
