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 series of air-stable NHC-Pd-PEPPSI-type complexes with unsymmetrical NHC ligand and a phenyl group in its backbone were successfully synthesized with high yields (82%-94%). The complexes were characterized by various spectroscopic techniques, including H-1 NMR, C-13 NMR, FT-IR spectroscopy, and HRMS. The crystal structure of the complexes was determined using single-crystal X-ray diffraction, showing a slightly distorted square planar geometry around the metal centre. The complexes exhibited excellent catalytic activities in Heck-Mizoroki and Suzuki-Miyaura cross-coupling reactions under low catalyst loadings.

Summary: Researching carbon dioxide removal from flue gas and natural gas is crucial. Metal-organic frameworks (MOFs) are commonly used in adsorption due to their high surface area, porosity, and chemical properties. An ultra-microporous MOF CPM-20(Co) with mixed ligand was synthesized using inexpensive ligands. The material exhibited high selectivities and low regenerative energy, making it a promising option for CO2 separation in industries.
