Abstract

Our research characterized the catalytic activity of Fe3O4@Arginine-Pd(0) nanoparticles in the Suzuki carbonylator reaction using Fe3O4@Arginine-Pd(0) nanoparticles synthesized in this study. Physicochemical characterization techniques including vibration sample magnetometry (VSM) and Brunauer-Emmett-Teller (BET) surface area analyzer were used to investigate, identify, and analyze these nanoparticles' surface functional groups, crystal structure, magnetic properties, size, and surface morphology. As an essential contributor to Pd nanoparticle stability and increasing electron density, arginine plays a very important role in preventing the leaching of Pd metal. Using Cr(CO)6 as a carbonyl source, the nanomaterial was prepared and used as a heterogeneous catalyst in the carbonylative Suzuki coupling reaction between aryl iodides and arylboronic acids. Catalysts were effective for efficient coupling reactions between various aryl iodides and arylboronic acids, resulting in excellent yields of diaryl ketones. A further advantage was that the catalyst could be easily recovered by filtration and reused for 6 cycles with no loss of structural integrity or catalytic activity.
