We report the design and development of a transition-metal-free cross-coupling reaction phenols primary amines using simple readily available multifunctional reagent. The reactions work by induced proximity electronic activation both nucleophile electrophile for net dehydrative C-N coupling reactions. Notably, do not involve use transition metal bond formation, preactivation phenol electrophile, or exclusion air moisture. mild conditions tolerate broad range functional groups allow this to be applied late-stage functionalization complex substrates with wide scope partners.

Novel palladium based magnetic nanocatalyst was synthesized by the co-precipitation method and coated with silica tea extract as stabilizing agent. Palladation onto prepared nanocomposite done to get ION-SiO2/TE-Pd(0) catalyst. Our study is one of limited number studies reported for catalytic denitrogenative coupling arylbromide arylhydrazine. This led construction important substituted biaryls bearing various substituents 82–92% yields. The characterized using structural morphological characterization techniques. It also observed that only 2 mol% catalyst sufficient catalysis reusable upto six cycles.

Abstract Palladium- and nickel-catalyzed cross-couplings are powerful methods for constructing C–C C–N bonds, particularly through Suzuki–Miyaura Buchwald–Hartwig reactions. Although aryl iodides, bromides, triflates the most commonly used substrates, chlorides less frequently utilized due to their lower reactivity. However, they appealing because readily available inexpensive. This short review highlights recent developments on of chlorides, using both homogeneous heterogeneous catalysis with palladium nickel. 1 Introduction 2 Cross-Couplings 2.1 Homogeneous Palladium Catalysis 2.2 Heterogeneous 2.3 Nickel 2.4 3 Amination Reactions 3.1 3.2 3.3 3.4 4 Conclusion

Declining natural resources make the recovery of metals from waste solutions a promising alternative. Moreover, processing into finished product has its economic justification and benefits. Thus, aim this research was developing Waste for Product strategy, indicating possibility with low content platinum-group catalyst synthesis. The results obtained confirmed that diluted synthetic containing trace amount valuable metal ions (Pd, Pt) can be used process Catalysts produced in form palladium platinum nanoparticles were successfully deposited on Ni foam due to galvanic displacement mechanism. Synthesized catalysts characterized using UV-Vis spectrophotometry, SEM/EDS, XRD techniques. Electro- catalytic properties tested hydrogen/oxygen evolution reactions methyl orange degradation, respectively. electrocatalytic tests indicated modification nickel surface by consisting noble as Pd Pt significantly increase activity hydrogen oxygen comparison non-treated samples. Catalytic performed degradation shorten time several hours 15 min. most favorable following order Pd1.0Pt0@Ni > Pd0Pt1.0@Ni Pd0.5Pt0.5@Ni no catalyst, best performance pure surface.
