Demonstrates enhanced catalytic activity in chemical reactions using polymer-stabilized palladium nanoparticles, suggesting a new method for efficient transformations.
Key Points
The aim is to synthesize polymer microgel-stabilized palladium nanoparticles and evaluate their catalytic efficiency in chemical reactions.
Synthesis of p(NPMAA) microgel particles via free radical precipitation polymerization.
Characterization using TEM, TGA, FT-IR, and XRD techniques.
Evaluation of catalytic activity for Suzuki-Miyaura coupling and nitroarenes reduction reactions.
Nitroarenes were converted to aryl amines with yields between 91% and 96%.
Suzuki-Miyaura coupling reactions produced biaryl compounds with yields ranging from 92% to 99% within 2 to 16 minutes.
The Pd-[p(NPMAA)] catalyst showed stability below 250 °C and effective recycling capabilities.
