Fe3O4@SiO2@Im[Cl]Mn(III)-complex as a highly efficient magnetically recoverable nanocatalyst for selective oxidation of alcohol to imine and oxime

One-pot green synthesis of iron oxide nanoparticles from Bauhinia tomentosa: Characterization and application towards synthesis of 1, 3 diolein

“…Magnetic nanoparticles that transpire to be promising practical support can trammel challenges faced by conventional NPs 10 . We can separate the magnetic NPs using a magnetic field, thereby improving their recovery, increasing the activity and stability, and also reducing steric hindrance 11 . An increase in particle stability reflects the correlation of green synthesized magnetic nanoparticles by availing the organic matter from various plant part extracts 12 , 13 .…”

Fe3O4@Sap/Cu(ii): an efficient magnetically recoverable green nanocatalyst for the preparation of acridine and quinazoline derivatives in aqueous media at room temperature

“…Therefore, according to the existing needs during the past decade, the design and development of environmentally friendly recyclable organo-catalysts with desirable structural diversity and high selectivity, has become a big challenge for researchers and scientists. [3][4][5] Hitherto, innovative catalysts have been developed as a fruitful strategy with the aid of natural organic compounds. 3,6,7 Saponins are a diverse group of plant amphipathic glycosides 8 consisting of steroid or triterpenoid aglycone attached to one or more sugar chains.…”

“…[3][4][5] Hitherto, innovative catalysts have been developed as a fruitful strategy with the aid of natural organic compounds. 3,6,7 Saponins are a diverse group of plant amphipathic glycosides 8 consisting of steroid or triterpenoid aglycone attached to one or more sugar chains. 9 The saponins structure can be seen in many plants; such as Sapindaceae, 10 Panax, 11 Gynostemma, 12 and Hippocastanaceae 13 (Fig.…”

Mg‐catalyzed one‐pot preparation of benzimidazoles and spirooxindoles by an immobilized chlorophyll b on magnetic nanoparticles

“…19‐629). [ 45 ] Coating the nanoparticles with silicate groups resulted in a slight decrease in peak crystallinity and the observation of amorphous peaks at 2 θ = 10.5° (Figure 4b). The chlorophyll b immobilization on the nanoparticles further reduced the peaks crystallinity related to the crystal structure of Fe 3 O 4 .…”
