A magnetically retrievable, efficient, and benign maghemite‐Cu nanocatalyst was synthesized from inexpensive precursors and applied for C−O, C−N, and C−S bond‐formation reactions. The obtained maghemite‐Cu nanocatalyst was characterized by various techniques such as XRD, X‐ray photoelectron spectroscopy, field‐emission gun SEM with energy‐dispersive spectroscopy, atomic absorption spectroscopy, TEM, high‐angle annular dark‐field scanning transmission electron microscopy, FTIR spectroscopy, and Mössbauer spectroscopy. Excellent catalytic activity, ease of recovery, and reusability without a significant loss of yield make the present protocol highly sustainable to deal with industrial and environmental concerns.

“…Kale and Jayaram have reported magnetically retrievable γ-Fe 2 O 3 /hydroxyapatite (HAP) nanoparticles for the cycloaddition reactions of alkyne, halide and azide in aqueous medium to 1,2,3-triazoles [52]. In general, these types of reactions are performed using Cu and Ru metal bearing catalysts [53,54].…”

Magnetically recyclable nano-catalysts and their use in aqueous media is a perfect combination for the development of greener sustainable methodologies in organic synthesis. It is well established that magnetically separable nano-catalysts avoid waste of catalysts or reagents and it is possible to recover >95% of catalysts, which is again recyclable for subsequent use. Water is the ideal medium to perform the chemical reactions with magnetically recyclable nano-catalysts, as this combination adds tremendous value to the overall benign reaction process development. In this review, we highlight recent developments inthe use of water and magnetically recyclable nano-catalysts (W-MRNs) for a variety of organic reactions namely hydrogenation, condensation, oxidation, and Suzuki-Miyaura cross-coupling reactions, among others.

Phyto-compounds facilitated synthesis of nanoparticles has created an exceptional impact in the formation of nanoparticles and is used for the synthesis of modern nano drugs. Ignorance about phytochemical composition particularly knowledge of the bio-active principle of medicinal plant restricts the demonstration of the real picture of the enhancement of any bio-efficacy. The present communication scientifically established anti-inflammatory bio-efficacy in seeds of the folk plant Madhuca longifolia and its significant enhancement by bio-active principle (saponin) loaded silver nanoparticles (S@AgNps). A family of four saponins has been explored quantified (3.59%) and characterized (Micro Mass ESI-TOF MS spectra). Synthesis of S@AgNps has been conducted in a green single step and thoroughly characterized. In-vivo assessment of antiinflammatory bio-efficacy has been carried out using carrageenan induced hind paw edema in Swiss albino mice model. Anti-inflammation bio-efficacy of native seed extract (15 mg/kg/bw) was found 46.84% which was further elevated and further rose to 56.10% by saponin at considerable low optimized dose (1.5 mg/kg/bw). Anti-inflammatory bio-efficacy was further successfully enhanced to (70.99%) by S@AgNps, almost close to that of reference drug (Diclofenac sodium; 76.42%). Saponin loaded silver nanoparticles (S@AgNps) prepared from the seed extract of the plant M. longifolia seem to be an ideal candidate for the development of complimentary herbal nanomedicine for antiinflammation.
