“…Graphene oxide (GO) supported magnetically separable Cu II ONPs were prepared by Mirabedini et al which depicted excellent reactivity for the synthesis of propargylamine . Initially they have prepared GO supported Fe II Fe 2 III O 4 NPs and further anchored with CuO to form the final nano catalyst Fe 3 O 4 NPs/GO–CuONPs (Scheme ).The percentage of iron and copper in the catalyst is 80.77 and 9.87 respectively.…”

Propargylamine and its derivatives are important skeletal structure for synthesis of many nitrogen containing active biological and pharmaceutical compounds. They are classically prepared from aldehyde, amine and alkyne (A3 coupling) which proved to be an exciting method since water is the only byproduct with the desired compound. Three component coupling strategies are very attractive research domain in organic chemistry during the past two decades for the synthesis of highly functionalized organic molecules. Molecular diversity in three component reactions ends up with several methods for drug discovery process towards the synthesis of structurally tailored heterocyclic compounds. These one pot transformation processes do involve simultaneous addition of reactants, reagents and catalyst. The reactions are generally carried out by employing several transition metal catalysts. Nanoparticles have shown their potential as catalysts in several fields of chemical research in modern era. Now, they have taken entry in multicomponent reaction system for playing the role of a catalyst. This review highlights a library of metal nanoparticles which have been used in recent years for synthesis of propargylamine and its derivatives via A3 coupling reactions.

nanocatalyst) was prepared by the co-precipitation method and characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray powder diffraction and Brunauer-Emmett-Teller surface area analysis. CuO/ ZnO/Al 2 O 3 nanocatalyst proved to be a very efficient catalyst on the synthesis of propargylamines under solvent-free conditions in high yields. Moreover, the catalyst can be recyclable without reducing catalytic activity up to five times.

“…These coupling reactions proceed in the presence of a catalyst such as gold, zinc, copper, silver, iron‐based catalysts . Recently, development of novel and efficient catalysts for promoting KA 2 and A 3 coupling reactions received growing attention and various catalysts including magnetic catalysts such as Fe 3 O 4 @Au nanoparticles, magnetically separable CuO nanoparticles supported on graphene oxide, Cu 2 O/nano‐CuFe 2 O 4 and hybrid catalysts such as Cu(II) Schiff base complex immobilized on graphene oxide, sulfonate‐based Cu(I) metal–organic frameworks, copper nanoparticles supported on starch micro particles, have been reported . Similarly, tetrazoles are one of the most significant intermediates used for the synthesis of more complicated compounds.…”

Taking advantageous of both g‐C3N4 and magnetic core‐shell hollow spheres, for the first time a heterogeneous and magnetically separable hybrid system was prepared through a novel and simple hydrothermal procedure and used for immobilization of bio‐synthesized Ag(0) nanoparticles. The hybrid system was fully characterized by using SEM/EDS, FTIR, VSM, TEM, XRD, TGA, DTGA, ICP‐AES, BET and elemental mapping analysis. The catalytic utility of the obtained system, h‐Fe2O3@SiO2/g‐C3N4/Ag, for promoting ultrasonic‐assisted A3, KA2 coupling reactions and [3 + 2] cycloaddition has been confirmed. The results established that the catalyst could efficiently catalyze the reaction to afford the corresponding products in high yields in short reaction times. The reusability study confirmed that the catalyst could be recovered and reused for at least five reaction runs with only slight loss of the catalytic activity. The hot filtration test also proved low silver leaching, indicating the heterogeneous nature of the catalysis.
