Description
Summary:The present work reports the design, synthesis, and characterization of palladium complex immobilized on chitosan/poly(o‐phenylenediamine) (CS‐PoPD‐Pd) for the catalytic application in the Suzuki–Miyaura CC cross‐coupling reaction through a nontoxic, inexpensive, eco‐friendly, and practical method. Fourier‐transform–infrared (FT‐IR) spectroscopy, scanning electron microscopy (SEM), energy‐dispersive X‐ray spectroscopy (EDX), elemental mapping, X‐ray diffraction (XRD), and inductively coupled plasma‐optical emission spectrometry (ICP‐OES) techniques were used for analyzing the prepared catalyst. Characterization studies showed that CS‐PoPD‐Pd was successfully synthesized according to our design. CS‐PoPD‐Pd composite demonstrated high product yield and high turnover number (TON) and turnover frequency (TOF) values with small catalyst loading for the Suzuki–Miyaura CC cross‐coupling reaction under mild reaction conditions. Besides, the synthesized CS‐PoPD‐Pd composite could be readily recycled and reused for at least five runs without discernible loss of its catalytic activity. CS was prepared via demineralization, deproteinization, and deacetylation of shrimp chell. Polymerization of o‐phenylenediamine on the CNS surface was done to create further active sites. CS‐PoPD‐Pd composite has been exhibited high performance for the Suzuki cross‐coupling reaction.
