•PdCl2 was immobilized on modified poly(styrene-co-maleic anhydride).•A quantitative description for metal–ligand interactions was determined.•The catalyst was successfully applied in Suzuki and Sonogashira reactions.•This catalyst can be loaded without pre-activation and reused.
The Suzuki–Miyaura and Sonogashira coupling were performed using a new, efficient, reusable and recyclable polymer-supported palladium catalyst. Poly(styrene-co-maleic anhydride) as polymer-support is modified with 2-aminothiazole. PdCl2 was immobilized on this prepared support and its appearance was confirmed by scanning electron microscopy (SEM), energy dispersive spectroscopy analysis of X-rays (EDAX), inductively coupled plasma (ICP) analysis, and FT-IR techniques. In addition, a quantitative description for metal–ligand interactions in the aforementioned polymer-supported palladium complex is investigated by performing theoretical calculations using density functional theory techniques.
