A rapid, one pot microwave assisted synthesis of nanosize cuprous oxide

NiO nanoparticles catalyzed three component coupling reaction of aldehyde, amine and terminal alkynes

“…Firstly, −NH 2 group of benzylamine reacts with nickel acetate to give A, which on rearrangement leads to the formation of nickel hydroxide and Nbenzylacetamide takes place. A similar type of mechanism has also been reported in literature [14,38].…”

“…The microwave process is more efficient than the conventional processes for preparation of various metal oxide nanoparticles [14,15]. The microwave associated synthesis enhances the kinetics of reactions by one or two orders of magnitude over conventional methods due to rapid initial heating and generation of localized high pressure zones at reaction sites.…”

Multi‐component reaction‐functionalized chitosan complexed with copper nanoparticles: An efficient catalyst toward A3 coupling and click reactions in water

“…The neat CS shows the characteristic peaks of typical fingerprints of semi crystallinity CS at 2θ values of about 11° and 20° . For the XRD pattern of CS‐MCR/Cu 2 O bio‐nanocomposite, the diffraction peaks at 2θ = 29.7°, 36.6°, 42.4°, 61.5° are respectively well corresponding to (110), (111), (200), (220) planes of cubic‐structured Cu 2 O . Besides, the wide peak at 2θ value of 11° and 20° are related to the typical nature of CS.…”

Magnetically separable γ-Fe2O3 nanoparticles: An efficient catalyst for acylation of alcohols, phenols, and amines using sonication energy under solvent free condition

“…The researchers paid their efforts to synthesis of magnetic s magnetic separable nanoparticles and their applications in catalysis [33][34][35]. In our recent work, we have developed several facile and greener synthetic routes for nanoparticles and developed their applications in catalysis [36][37][38][39][40]. In the present work, we have developed an efficient method for the synthesis of γ-Fe 2 O 3 nanoparticles by thermolysis method.…”
