摘要

This study details the efficient synthesis of superparamagnetic nanoparticles functionalized with a Pd-EDTA complex using a simple and effective method. Comprehensive characterization of the resulting heterogeneous catalyst was performed through techniques such as TEM, XPS, XRD, FE-SEM, VSM, FT-IR, ICP, and EDX, with precise palladium content measurement achieved via ICP. The immobilized palladium complex showed remarkable catalytic performance in esterifying aryl aldehydes. The system presents notable advantages, including ease of handling, reduced reaction times, and convenient magnetic separation, facilitating straightforward catalyst recovery. Additionally, the catalyst demonstrated exceptional recyclability, retaining high activity across several cycles. Although the study primarily focused on aryl aldehydes, the reactions consistently achieved excellent isolated yields, highlighting the potential of this magnetic system in sustainable and efficient fine chemical synthesis.
