Palladium Supported on Porous Organic Polymer as Heterogeneous and Recyclable Catalyst for Cross Coupling Reaction

Abstract

Palladium immobilized on an amide and ether functionalized porous organic polymer (Pd@AEPOP) is reported to be an effective heterogeneous catalyst for the Heck cross-coupling reaction of aryl iodides with styrene for the synthesis of diphenylethene derivatives. Excellent yields can be obtained using a 0.8 mol% Pd catalyst loading under the optimized reaction condition. The heterogeneous Pd@AEPOP catalyst can also be applied on the Suzuki reaction and the reduction of nitroarene.

In situ palladium-doped conjugated polymer network for visible light and natural sunlight-driven Suzuki type cross-coupling reaction at room temperature

“…27 Recently, porous architectures such as porous polymers which include porous organic polymers (POPs), organic polymer networks, covalent organic frameworks, and metalorganic frameworks have emerged as promising contenders in the field of heterogeneous catalysis. 28 Recently, there have been reports of Pd-anchored porous organic polymers for Suzuki-Miyaura coupling reactions, [29][30][31][32][33] where reactions are generally performed through energy-intensive heating protocols (temperature ranging from 60 °C to 150 °C). Therefore, harnessing visible light or more suitably natural sunlight as an energy source to perform such reactions attained considerable research attention due to environmental, economic, and industrial viability.…”

Automated Recognition of Nanoparticles in Electron Microscopy Images of Nanoscale Palladium Catalysts

“…One of the most critical commercial catalysts is palladium on carbon (Pd/C). As a few examples, it can catalyze various reactions, including [ 2 ] but not limited to hydrogenations [ 3 ], hydrogenolysis [ 4 ], cross-coupling [ 5 , 6 ], and others [ 7 ]. The highest catalyst performance with ~10 9 turnover numbers was recently achieved with Pd/C catalysts [ 8 ].…”
