Summary: This study reports the design, synthesis, and application of naturally occurring cellulose from agro waste pomegranate peel as a novel support for active biogenic Pd nanoparticles for Suzuki-Miyaura and Sonogashira cross-coupling reactions at room temperature. The cellulose matrix enables well dispersion of Pd nanoparticles over the support to generate Pd@cellulose, exhibiting excellent catalytic activity and recyclability under ligand-free mild reaction conditions. The synthesized cellulose nanofibers and Pd-anchored heterogeneous nanofibers were characterized through various analytical techniques.

Summary: Suzuki-Miyaura cross-coupling reaction is a powerful method to construct carbon-carbon bonds and is widely used in the synthesis of functional organic compounds. In this study, zeolite-encased Pd particles (Pd@MFI) were successfully prepared and investigated as promising heterogeneous catalysts for the Suzuki-Miyaura cross-coupling reaction. The Pd@MFI catalysts showed high activity, with dispersed Pd particles efficiently stabilized within the MFI zeolite matrix. The presence of basic sites adjacent to Pd sites was crucial for achieving high catalytic activity.

Summary: A hetero-binuclear complex Ir-Pd was obtained by the reaction between iridium complex and (CH3CN)PdCl2 via ortho-metallation. This complex showed excellent catalytic activity for Suzuki-Miyaura and Sonogashira cross coupling reactions under blue LED irradiation. The effects of photochemical conditions on these coupling reactions catalyzed by Ir-Pd were studied.

Summary: In recent years, there has been extensive research on immobilizing palladium nanoparticles on solid supports for the preparation of active and stable catalytic systems. Compared to inorganic materials, naturally occurring organic solids are more cost-effective and readily available. This review focuses on the application of metal catalysts supported by natural biomaterials in C-C bond formation reactions, specifically Mizoroki-Heck, Suzuki-Miyaura, and Sonogashira reactions. Different types of organic matrices, such as cellulose, starch, pectin, agarose, chitosan, as well as proteins and enzymes, are discussed, highlighting the heterogeneous nature and recyclability of each catalyst.

Summary: A novel Pd(II)-polymeric pre-catalyst was successfully prepared and demonstrated good activity in the Suzuki-Miyaura coupling reaction. The catalyst showed recyclability and its performance was affected by the concentration of the cross-coupling partners. The presence of oxygen was found to be crucial in preventing the formation of inactive Pd(0) aggregates.

Summary: The distorted honeycomb-like hollow cage-structured bio-nanocellulose, derived from cellulosic waste of pomegranate peel using a simple microwave technique, can be loaded with Pd nanoparticles and utilized as an efficient heterogeneous catalyst for the synthesis of potential bioactive derivatives via cross-coupling reactions. The catalyst is reusable up to five catalytic cycles without significant loss of its activity.

Summary: This study reports the synthesis of the first Ni-based ZIFs and demonstrates their high potential as heterogeneous catalysts for the Suzuki-Miyaura cross-coupling reaction. The presence and arrangement of the carbonyl functional groups on the imidazole linker play a crucial role in completing the preferred octahedral coordination of nickel, providing a promising platform for the rational design of Ni-based ZIFs for a wide range of catalytic applications.

Summary: This study synthesized and compared the performance of 2D imine COFs as catalysts, finding that Pd@TTA-DFB COF exhibited fast reactivity but low stability, Pd@TTA-DFP COF had the highest stability but slowest reactivity, and Pd@TTA-TBD COF showed the best overall performance. Experimental and computational results indicated that the reduction from Pd(II) to Pd(0) is a key step in determining the catalytic activity of COFs.

Summary: Palladium has been widely used in the Suzuki-Miyaura cross coupling reaction for over 30 years, but it comes with drawbacks such as high cost, tedious work-ups, product contamination, and metal leaching. In recent years, other metals like Ni, Cu, Co, Fe, Rh, and Ru have attracted attention for their potential in SMCR, allowing for the synthesis of industrially important compounds with various functional groups. This review discusses recent advancements in catalysis related to SMCR, providing valuable insights for researchers in designing synthetic protocols for pharmacophores and drug molecules.

Summary: In this study, a new heterogeneous catalyst Pd-NHC@Eu-BCI was synthesized by incorporating N-heterocyclic carbene-palladium active sites into a 2D coordination polymer based on a 1,3-bis(carboxymethyl)imidazolium ligand. The catalyst was thoroughly characterized using various analytical techniques. The Pd-NHC@Eu-BCI catalyst exhibited excellent catalytic activity in the Suzuki-Miyaura cross-coupling reaction. It could be easily recovered from the reaction mixture and maintained its catalytic activity and structure even after five cycles.
