A new mononuclear nickel complex with 5,5′-dimethyl-2,2′-bipyridine: Synthesis, structural investigation and catalytic properties

A novel core@double-shell three-layer structure with dendritic fibrous morphology based on Fe3O4@TEA@Ni–organic framework: a highly efficient magnetic catalyst in the microwave-assisted Sonogashira coupling reaction

“…Finally, through reductive elimination and regeneration of the catalyst's starting state, the desired product is produced from the C species. 45 Based on the following mechanism, the active sites of the fabricated catalyst can be considered as Ni( ii ) ions that directly catalyze the Sonogashira coupling reaction.…”

Pd supported on locust bean gum as reusable green catalyst for Heck and Sonogashira coupling reactions and 4‐nitroaniline reduction under ultrasound irradiation

“…However, at an amplitude value of 40%, the obtained yield decreased, which seems to correspond to the threshold of the physical limit of the ultrasonic activation. [46,47] The effect of ultrasound increased with the amplitude used until a maximum value, which is the cavitation threshold. From this level, the cavitation is very intense.…”

Supramolecular architectures of mononuclear nickel(II) and homobinuclear copper(II) complexes with the 5,5′-dimethyl-2,2′-bipyridine ligand: Syntheses, crystal structures and Hirshfeld surface analyses

“…On the basis of the aforementioned thoughts and as an expansion of our research on supramolecular architectures of the 5,5'-dimethyl-2,2'-bipyridine based salts, in which aromatic N play a key vital role in generating threedimensional (3D) networks through π…π stacking interaction. 33 In the present work, we report the synthesis, spectroscopic characterization and X-ray crystal structures of two new Ni(II) and Cu(II) coordination complexes as well as a deep analysis of their interesting crystalline architectures formed by supramolecular interactions.…”
