Abstract

In the present work, we invented a Pd nanoparticle immobilized on an amine-functionalized LDH catalyst (PdNP@NH2-LDH-Al-MCM-41) for cross-coupling reactions. The palladium was grafted onto the support by treating the Pd(OAc)2 with NH2-LDH-Al-MCM-41 in acetone at room temperature. The prepared catalyst was characterized by FT-IR, SEM, TGA, TEM, and XPS techniques. The TEM characterization of the catalyst showed the uniform distribution of PdNPs with sizes ranging from 3 to 6 nm located inside the mesoporous. The Suzuki–Miyaura cross-coupling reaction was used to demonstrate the catalytic efficiency of the prepared PdNPs@NH2-LDH-Al-MCM-41 catalyst. The prepared and analyzed catalyst showed good to excellent activity in the Suzuki–Miyaura cross-coupling reaction of various aryl bromides with different aryl boronic acids in ethanol at 80 °C. The catalyst showed TON up to ~ 47 and TOF ~ 47 h−1. The catalytic results exhibited that the catalyst is completely recoverable with simple filtration. The catalytic efficiency shows a slight decrease in activity for the Suzuki–Miyaura cross-coupling reactions even after five repeated recycles. TEM images of the freshly prepared and reused catalysts (after five catalytic cycles) showed palladium nanoparticles remain unchanged at the end of the reactions.
