Copper is less expensive and has more readily available resources than many other transition metals, making it accessible. Loading nano-sized copper particles on the surfaces of support materials or obtaining nanoparticles based reduction processes just metal using them as nanocatalysts an interesting research area. Copper-based produced in various ways have been effectively employed a wide range organic chemical processes. We will demonstrate how copper-based are used chemistry such oxidation, reduction, click chemistry, Ullman-type cross-coupling reactions, cyclization reactions. To stay current work this field, we concentrated providing most recent scientific breakthroughs section, which include articles published between 2016 2023. The number obtained, well significant recommendations, were gathered from selected incorporated into chapter.

Although C–H functionalization is one of the simplest reactions, it requires use highly active and selective catalysts. Recently, C–H-active transformations using porous materials such as crystalline metal-organic frameworks (MOFs) covalent-organic (COFs) well amorphous porous-organic polymers (POPs) new emerging heterogeneous catalysts have attracted significant attention due to their promising activity potential material tunability. These solids offer exceptional structural uniformity, facile tunability permanent porosity. In addition, tuning catalytic selectivity these can be achieved through engineering site microenvironments, metal node substitution, linker changes, node/linker functionalization, pore modification. The present review provides an overview current state art on MOFs, COFs POPs advanced for various bond activation providing details about chemo-, regio-, stereo-selectivity control, comparing performance with that other catalysts, triggering additional research by showing limitations challenges in this area, a perspective future developments.

N-heterocyclic carbene (NHC) silver(I) and gold(I) complexes have found different applications in various research fields, as medicinal chemistry for their antiproliferative, anticancer, antibacterial activity, innovative effective catalysts. The possibility of modulating the physicochemical properties, by acting on ligands substituents, makes them versatile tools development novel metal-based compounds, mostly anticancer compounds. As it is known, chemotherapy commonly adopted clinical treatment cancers, even though its efficacy hampered several factors. Thus, more less toxic drugs still an urgent need. Herein, we reported synthesis characterization new stabilized caffeine-derived NHC ligands, together with biological catalytic activities. Our data highlight interesting properties this series catalysts A3-coupling hydroamination reactions promising anti-inflammatory, antioxidant agents. ability these regulating pathological aspects, often co-promoting causes, cancer ideal leads to be further structurally functionalized investigated.
