Polymer‐supported palladium: A hybrid system for multifunctional catalytic application

Abstract

Polymer-supported palladium was synthesized by applying a single-step wet chemical synthesis route and the resultant composite material was characterized by means of various techniques. Infrared and UV-visible spectra provided information on the chemical structure of the polymer. Microscopy techniques showed the general morphology of the polymer. The oxidation state of palladium was determined using the X-ray photoelectron spectroscopy method. The synthesized material was applied as a heterogeneous catalyst for the Heck coupling reaction and also as an electrocatalyst for the oxidation of cysteine.

The Current Status of Heterogeneous Palladium Catalysed Heck and Suzuki Cross-Coupling Reactions

“…Literature reports have repeatedly shown that palladium nanoparticles can be efficiently supported on polymer frameworks [ 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 ]. Recently, Nemygina and co-workers immobilised various palladium precursors (PdCl 2 , PdCl 2 (CH 3 CN) 2 , and PdCl 2 (PhCN) 2 ) on amino-functionalized hyper-crosslinked polystyrene [ 78 ].…”

Pd@GO catalyzed stereo- and regio-selective addition of arenes to alkynes and synthesis of coumarins via C–H functionalization

“…Solid supported palladium nanoparticles (Pd NPs) have widespread applications in catalysis, mostly for classical C–C coupling reactions, due to their high stability, narrow size distribution, and large surface area. 8 In this paper, Graphite Oxide (GO) was used as a solid support to anchor the Pd nanoparticles on its surface. GO contains a variety of functional groups like carboxyl, hydroxyl, and epoxy groups.…”
