Solid phase one-pot Multicomponent reaction was used widely to achieved a board spectrum of heterocyclic compounds due to it’s supreme properties starting from four component mixture of piperonal binzil, p-phenylene diamine and ammonium acetate which was reacted directly through grinding then microwave irradiation at (270 watt) for (8 min) in a cidic media to afford 1-N(p-aminophenyl)-2-(piperonyl-5-yl)-5-hydroxy-4, 5-diphenyl-2H-imidazole (1) which then converted to its N'-aroyl derivatives (2-4) through it’s reaction with substituted benzoyl chloride in basic media terminated by direct reaction with acetic anhydride to obtained N'-acetyl-N'-aroyl derivative (5-7) followed by inter cyclization reaction with hydrazine hydrate (99%) to achieve 1,2,4-trizole derivatives (8-10) in basic media. The assigned structure of the prepared compounds were corroborated by the available physical and spectral methods.

“…The coating of MNCs with large molecules which are sterically Fig. 1 Comparison of the nanocatalys with homogeneous and heterogeneous catalysts crowed, charged and functional polymers can also protect the agglomeration and improve their stability in aqueous media (Rossi et al 2014;Díaz-hernández et al 2018;Chen et al 2020;Escoda-torroella et al 2021;Gebre 2021). Indeed, the attached ligands have multiple functions which offered additional benefit such as increasing activity at the core of the metal, synergistic effect, and their binding ability towards the metal is crucial for the long-term stability of the nanocatalyst.…”

Designing and building an ideal catalyst for organic reactions is needed to increase the efficiency, reaction conditions, and to reduce its environmental impacts. The growth of nanotechnology is realized in the production of various nano-level catalysts for different applications. The as-synthesized nanocatalysts are easily manipulated to a desired shape and size with a high surface area to volume ratio, which is their critical property of the interaction of the nanomaterials with the substrates. These days, a vast array of catalysts (nanocatalysts) such as metals, metal oxides, magnetic, and alloyed/mixed nanocatalysts are applied in organic reactions to synthesize important chemicals in industries and pharmaceutical sectors with a high yield, selectivity, and reusability via reduction/hydrogenation, oxidation, condensation, C-C coupling, cyclization, and more. Consequently, this present review highlights the application of various nanocatalysts in organic reactions by combining certain proposed reaction mechanisms that have shown the impact of nanoparticles on the reactions. The factors influencing nanocatalyst performances are also discussed. Finally, the conclusion and future prospects are conveyed.
