Immobilized ionic liquids on Fe3O4 nanoparticles: A potential catalyst for organic synthesis

An Exploration on Copper‐Based Metal‐Organic Frameworks as Propitious Heterogeneous Catalyst for Coupling Reactions

“…[106] T. A. To and co-workers synthesized the copper composed MOF Cu 2 (OBA) 2 (BPY) (XVII) and employed it as a practicable heterogeneous catalyst for the direct formation of CÀ S type bond to produce b-sulfonylvinylamines (64) from sodium sulfinates (62) and oxime acetates (61). The solvent had a significant influence on the reaction, and chlorobenzene arose as the excellent choice.…”

“…[54] Furthermore, benzoazoles, [55] indolizines, [56,57] a-ketoamides, [58][59][60] and their analogues are crucial basic components that are present in a variety of ecologically active molecules, agrochemicals and natural materials that can also be synthesized via CÀ N coupling processes. [61,62] Crystalline porous MOF Cu-MOF-74 (I) was derived and characterized by T. Truong et al, and then employed in the oxidative dehydrogenative coupling of amines (2) and a-carbonyl aldehydes (1) to produce a-ketoamides (3). When a catalytic quantity of Cu-MOF was present, high yields were obtained even in the absence of ligand and base.…”

“…The three main methods for producing imines (C−N coupling) are cross‐coupling of alcohols and amines through oxidation process, [51,52] self‐coupling of primary amines, [53] and oxidative dehydrogenation of secondary, amines in which the first method appears to be the most promising [54] . Furthermore, benzoazoles, [55] indolizines, [56,57] $${\alpha }$$ ‐ketoamides, [58–60] and their analogues are crucial basic components that are present in a variety of ecologically active molecules, agrochemicals and natural materials that can also be synthesized via C−N coupling processes [61,62] …”

Advancement in utilization of magnetic catalysts for production of sustainable biofuels

“…Recently, due to their highly tunable nature, low volatility, and strong chemical and thermal stability, ionic liquids (ILs) have been widely reported for use in the catalysis field ( Sharma et al, 2022 ). Among these, many IL-functionalized magnetic catalysts have been tested for the production of biodiesel because of their unique properties and commercial availability.…”

Biogenic synthesis of δ‐MnO2 nanoparticles: A sustainable approach for C‐alkylation and quinoline synthesis via acceptorless dehydrogenation and borrowing hydrogen reactions

“…Because of their unique physicochemical and diverse biological properties, metal-oxide nanoparticles are largely used for various applications in different field, such as biomedicine, water remediation, and organic transformation. [16][17][18][19][20][21] In this context, a wide range of mono- 22,23 and bimetallic oxide nanoparticles [24][25][26][27][28] such as Pd, Pt, Au, Ag, Fe, Mn, Cu, and Zn, along with combinations of Cu/Au, Ag/Au, and Au/Pd, have been synthesized using a large variety of plant materials with noble and transition metal configurations. However, despite the potential catalytic and medicinal activities, the noble metal catalysts possess demerits such as: (a) limited earth abundance; (b) difficult extraction processes; (c) toxicity and high cost.…”
