A facile and rapid route for the synthesis of Cu/Cu₂O nanoparticles and their application in the Sonogashira coupling reaction of acyl chlorides with terminal alkynes

Abstract

This work reports a simple, rapid and efficient protocol for synthesis of Cu/Cu2O nanoparticles. The prepared Cu/Cu2O nanoparticles were effectively utilized for Sonogashira coupling reaction of acyl chlorides with terminal alkynes.

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.…”

Cu‐Based Nanocomposites as Multifunctional Catalysts

“…Compared to other reports [30,51,52,62,63] on the Sonogashira cross-coupling reaction, we have used lower amount of catalyst to give ah igh yield of product. For the different aryl iodides, electron-rich as well as electron-deficient aryl iodides were successfully converted into the cross-coupled products.T hese results are summarized in Ta ble 3.…”

Ultrasound‐Assisted Preparation of Copper(I) Oxide Nanocubes: High Catalytic Activity in the Synthesis of Quinazolines

“…[9] It has been well documented that the morphology and microstructure of Cu 2 On anoparticles can be controlled by modifying the reaction conditions and starting materials by using, for example, different capping agents, reducing agents, precursors, reaction temperatures,p Hv alues, ultrasonication, and microwaves. [1,6,11] As an ew strategy, the sonochemicalt echnique has been given much attention to prepare various inorganic nanomaterials such as monometallics, bimetallics, carbides,a nd oxides. [12] Different from other conventionalchemical methods, the sonochemicalt echnique is based on acoustic cavitation phenomena.…”
