Gold Nanoparticles-Decorated Dithiocarbamate Nanocomposite: An Efficient Heterogeneous Catalyst for the Green A3-Coupling Synthesis of Propargylamines

Synthetic application of gold complexes on magnetic supports

“…Many nanocatalysts, including Cu, Zn, Ti, Ni, and Au, have been used for the preparation of propargylamines. The use of nonmagnetic Au catalyst for A 3 coupling has already been reported . But a novel magnetic Au catalyst has also been reported for the first time that benefits from caffeine as a modification on the solid support .…”

Carbon–nitrogen bond formation using modified graphene oxide derivatives decorated with copper complexes and nanoparticles

“…Catalytic activity of transition metals for carbon–nitrogen bond formation has been approved during the years. [ 33 ] Synthesis of propargyl amines by gold nanoparticles (NP)‐decorated with dithiocarbamate, [ 34 ] one‐pot synthesis of amidoalkyl naphthols using magnetic nanoparticles (MNP)‐supported acidic ionic liquid, [ 35 ] synthesis of tetrahydropyridines by silver, iron, and nickel immobilized on hydroxyapatite‐core–shell γ‐Fe 2 O 3 MNPs, [ 36 ] construction of pyrimido[1,2‐ b ]indazole derivatives by silver NPs, [ 37 ] and synthesis of pyrazolopyridocoumarin scaffolds by zinc chloride [ 38 ] are some examples of transition metals' applications for carbon–nitrogen bond formation. Furthermore, copper and palladium transition metal complexes were investigated as catalysts or stoichiometric agents in C–N cross‐coupling reactions using ligand or ligand‐free conditions.…”

A Novel Recyclable Ni/Cu/Fe Termetallic Nanocatalyst for the Synthesis of Propargylamines through the A3‐Coupling Reactions

“…Recently, some heterogeneous nanoparticles have been reported as the efficient catalytic systems for the A 3 ‐coupling reactions of aldehydes, amines, and terminal alkynes . Heterogeneous magnetic nanoparticles catalytic systems are more popular due to fast and cost‐effective separation of the catalyst from the reaction medium by applying an external magnetic field.…”

“…Recently, some heterogeneous nanoparticles have been reported as the efficient catalytic systems for the A 3 -coupling reactions of aldehydes, amines, and terminal alkynes. [21][22][23][24][25] Heterogeneous magnetic nanoparticles catalytic systems are more popular due to fast and cost-effective separation of the catalyst from the reaction medium by applying an external magnetic field. More recently, some methods have been successfully developed which use nickel and nickel oxide nanoparticles as the efficient catalysts for A 3 -coupling reactions.…”
