Abstract
This study presents the synthesis and application of palladium nanoparticles (Pd NPs) supported on ionic-liquid-functionalized periodic mesoporous organosilica (PMO-IL) as an efficient heterogeneous catalyst for carbonylative Suzuki coupling reactions. The PMO-IL material was prepared via a sol-gel polycondensation process using tetraethyl orthosilicate (TEOS) and a bis-silylated ionic liquid monomer. The ionic liquid groups within the PMO framework facilitated the adsorption of palladium salts through ion exchange, followed by reduction to form Pd NPs. Comprehensive characterization of the Pd(np)@PMO-IL system, including high-resolution microscopy (HR-SEM and HR-TEM), X-ray diffraction (XRD), solid-state NMR, FT-IR, and nitrogen adsorption-desorption (BET) analyses, confirmed its structure, morphology, and high surface area. The catalytic system demonstrated remarkable activity, selectivity, and recyclability in the carbonylative Suzuki coupling reaction, achieving high turnover numbers (TON) and turnover frequencies (TOF) under mild conditions. This hybrid material highlights the potential of ionic liquid-functionalized PMOs as versatile supports for metal nanoparticles in sustainable catalytic applications.
