Preparation and Characterization of Nanocopper Ferrite and Its Green Catalytic Activity in Alcohol Oxidation Reaction

Two different facile and efficient approaches for the synthesis of various N-arylacetamides via N-acetylation of arylamines and straightforward one-pot reductive acetylation of nitroarenes promoted by recyclable CuFe2O4 nanoparticles in water

“…Furthermore, compared with iron oxides, spinel ferrites provide flexibility to control both crystal structures and magnetic properties by choosing different non-iron metals in spinel ferrite backbone and controlling their molar concentrations. Among various type of spinel ferrite magnetic nanoparticles (MNPs), CuFe 2 O 4 nanocomposite, in addition to numerous applications, has shown satisfactory performance as the recyclable catalyst in various organic transformations such as synthesis of heterocyclic compounds [46][47][48][49][50][51][52], Ullmann C-O coupling reaction [53], direct synthesis of chemical structures containing both phenol ester and benzothiazole moieties via dehydrogenative coupling reactions [54], reduction of p-nitrophenol [55], one-pot odorless carbon-sulfur bond formation reactions [56], directed phenol/formamide coupling [57], synthesis of diaryl/aryl alkyl sulfides via cross-coupling process [58], S-arylation of thioureas by aryl halides [59], one-pot four-component Dakin-West reaction (synthesis of β-acetamido ketones) [60], Friedel-Crafts acylation [61], N-arylation of heterocycles [62], direct C-H amination of benzothiazoles [63], oxidative hydroxylation of arylboronic acids [64], palm oil methanolysis [65], oxidation of benzyl alcohol [66], synthesis of unnatural arundines [67], N-arylation of indole and imidazole with aryl halide [68], and so on.…”

Sonochemically induced cube-shaped NiFe2O4 nanoparticle-catalyzed selective oxidation of benzyl alcohol to benzaldehyde

“…3 At the present time, numerous efforts are being made toward the selective oxidation of alcohol to carbonyl compounds using such spinel ferrites. [44][45][46][47][48] In our previous work, we reported the synthesis of NiFe 2 O 4 and MnFe 2 O 4 NPs and successfully used them in the selective oxidation of benzyl alcohol to benzaldehyde. 24,31 Motivated by the previous reports, we examined the catalytic activity of the cube-shaped NiFe 2 O 4 NPs in the selective oxidation of benzyl alcohols to benzaldehydes, expecting that it would offer better performance.…”

Synthesis of Transition Metal Ferrites (Co, Cu, Ni, Mn) by the Sol-Gel Method with Combustion and the Use of Microwave Processing

“…Microwave technology is used in the synthesis of ferrites by the sol-gel method with combustion at the stage of drying and combustion. The literature data analysis shows that it is also possible to synthesize nanosized ferrites through the use of microwave radiation in the sol-gel method with combustion [17][18][19][20][21][22]. The brief review of recent works presents data on the synthesis of a number of ferrites (Co, Ni, Cu, Mn) by the sol-gel method with combustion, as well as using microwave treatment as an initiator of the combustion reaction, i.e.…”
