The complex has been characterized by FT-IR, EDS, XRD, TEM, HRTEM, Raman, ICP-OES and elemental mapping analyses. Pd NPs@CS-UN was used as a catalyst for Sonogashira coupling reactions between aryl halides and acetylenes, employing K2CO3 as the base and EtOH as a green solvent under aerobic conditions in which it showed high efficacy. Pd NPs@CS-UN was regenerated by filtration after the completion of the reaction. This catalytic process has many advantages including simple methodology, high yields, and easy work-up. The catalytic performance does not notably change even after five consecutive runs.eninfo:eu-repo/semantics/embargoedAccessBiopolymer-supported Pd ComplexCatalysisChitosanSonogashira Coupling ReactionUnye BentoniteArticle262---10.1016/j.carbpol.2021.11792033838799Q1WOS:000639092700005Q1
