Preparation of gold nanoparticles decorated UiO-66-NH₂ incorporated epichlorohydrin and cyclodextrin as novel efficient catalyst in cross coupling and carbonylative reactions.

ABSTRACT: This study presents a new, highly effective, and reusable catalyst: UiO-66-NH₂@Epichlorohydrin@Cyclodextrin@Au-NPs. This innovative catalyst starts with the Zr-based UiO-66 material, which is functionalized with amino groups (-NH₂). We enhanced its surface compatibility by modifying it with epichlorohydrin and cyclodextrin via a post-synthesis modification method. Gold nanoparticles were then stabilized on this modified composite, resulting in the UiO-66-NH₂@Epichlorohydrin@Cyclodextrin@Au-NPs complex. We used this catalyst for C-C coupling and Carbonylative Sonogashira reactions in mild conditions. Its effectiveness was underscored by various analytical techniques, including XRD, EDS, SEM, FT-IR, TEM, BET, ICP, TGA, and elemental mapping. The catalyst exhi
