“…Maham and Nasrollahzadeh [76] further put forward a green synthetic strategy for the one-pot synthesis of 1-substituted 1H-1,2,3,4-tetrazoles 173 using Cu/bone nanocomposite as a heterogenous catalyst under solvent free condition. The nanocatalyst recycled and reused for four runs and exhibits no significant change in its morphology, shape and size studied by XRD (Scheme 68).…”

The field of reusable nano‐catalysts has grown rapidly over the last decade. Recently, transition metal catalysed organic reactions have attracted considerable interest from the pharmaceutical and organic chemistry fields. Synthetic procedures based on such heterogeneous nanocatalysts are easier, less expensive, non‐toxic, and eco‐friendly, producing only the most desirable products in higher yields and allowing for easy catalyst separation. Heterogeneous nano‐catalysts were highly preferred over homogeneous catalysts for the synthesis of heterocyclic compounds due to their effective separation processes for both products and catalysts. According to recent studies, nanoparticles (NPs) are commonly used as a heterogeneous catalyst in the production of heterocyclic compounds. Heterogeneous catalysts are widely used in a variety of organic reactions due to their high surface‐to‐volume ratio. Most importantly, after the reaction is complete, easy magnetic separation of the catalyst minimises the requirement for catalyst filtration. Additionally, magnetic NPs, particularly supported magnetic nanocatalysts, have garnered considerable interest in both academic and industrial research due to their effectiveness as alternatives to traditional materials, their ease of separation via an external magnet, and their high degree of chemical stability in a variety of organic and inorganic solvents. To reach its depth, this review is focused on the most recent examples, their preparation, synthetic strategies and recycling studies of highly excited catalytic systems used for the synthesis of heterocyclic compounds.

“…Full characterization by PXRD and XPS showed CuO nanoparticles were prepared as well through thermal decomposition of a welldefined copper complex using a thiazole picolinamide ligand [212]. The as-prepared material reacted in water to produce the corresponding triazoles with moderate to excellent isolated yields (41-95%), showing a remarkable activity compared to other supported catalytic systems [199]. Nasrollahzadeh et al reported the synthesis of CuNPs using Otostegia persica leaf as both stabilizer and reducing agent, taking advantage of the presence of flavonoids and phenolic compounds present in the plant [213].…”

Palladium and Copper: Advantageous Nanocatalysts for Multi-Step Transformations

Metal nanoparticles have been deeply studied in the last few decades due to their attractive physical and chemical properties, finding a wide range of applications in several fields. Among them, well-defined nano-structures can combine the main advantages of heterogeneous and homogenous catalysts. Especially, catalyzed multi-step processes for the production of added-value chemicals represent straightforward synthetic methodologies, including tandem and sequential reactions that avoid the purification of intermediate compounds. In particular, palladium- and copper-based nanocatalysts are often applied, becoming a current strategy in the sustainable synthesis of fine chemicals. The rational tailoring of nanosized materials involving both those immobilized on solid supports and liquid phases and their applications in organic synthesis are herein reviewed.

“…In 2018, Kanaani and Nasr-Esfahani prepared and characterized maleic anhydride coated magnetite nanoparticles (Fe 3 -O 4 @APTES-MAH NPs) and nanorod vanadatesulfuric acid (VSA NRs) as Brønsted acid nanocatalysts. Subsequently, their catalytic activity was examined for the synthesis of new 4-iminoquinolines (236) via the one-pot three-component reaction of equimolar amounts of 2-aminobenzonitrile (234), orthoesters(4,5), and active methylenes(235) under solvent-free conditions at 80 C. In this reaction the inuence of different parameters, such as the type of catalyst and orthoesters, was examined. It was found that both VSA NRs and Fe 3 O 4 @APTES-MAH NPs catalysts yielded the corresponding 4-iminoquinolines(236) in good to excellent yields.…”
