Development, Characterization and Catalytic Evaluation of New Nanosized metal complexes — •Tarek El-Dabea — Chemistry Department, Faculty of Science, King Salman International University, Ras Sudr, Sinai 46612, Egypt

A series of novel nano metal complexes involving Pd(II), Cu(II), Fe(III) and Ag(I) ions were synthesized using a Schiff base ligand in a bidentate coordination mode. The structural and molecular characteristics of these complexes were thoroughly characterized via an array of spectroscopic and analytical techniques, confirming molecular geometry and stoichiometry. Solution stability and stoichiometry of the complexes were systematically evaluated, demonstrating stable metal-ligand coordination. Notably, the Pd(II) complex exhibited unique electronic characteristics, identifying it as a promising candidate for catalytic applications. Based on these results, the Pd(II) complex was tested as a catalyst for synthesizing Different multicomponent reactions. This was achieved through using microwave irradiation. The selection of Pd(II) was informed by its favorable catalytic profile and theoretical insights. Optimization trials demonstrated that the Pd(II) catalyst afforded high yield and efficiency under eco-friendly (H*O/EtOH) solvent conditions. Reusability assessments showed that the catalyst retained high activity for up to five cycles, with minimal performance decline afterward. A mechanistic pathway was proposed, highlighting Pd(II)'s ability for axial coordination, supported by theoretical evidence
