Gold nanoparticles decorated magnetic dithiocarbamate nanocomposite (Au@CS2–AP@Fe3O4) led to a suitable catalyst for the propargylamines synthesis via A3-coupling reaction in water. The prepared catalyst was characterized by Fourier-transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction, atomic absorption spectroscopy, scanning electron microscopy, and energy-dispersive X-ray

Mercaptofunctionalized MCM-41 (MCM-SH) was obtained via reaction of MCM-chloride with mercaptoethanol. Then, gold nanoparticles supported on MCM-SH (Au@HS-MCM nanocomposite) were prepared by chemical reduction of HAuCl4 by NaBH4. The obtained catalyst was used as an effective and reusable heterogeneous catalyst in three-component coupling of aldehydes, alkynes, and amines (A(3)-coupling) in water. The catalyst could be recovered and reused several times without a significant loss of activity. (C) 2015 Elsevier B.V. All rights reserved.

formation from aldehydes and alkynes, a new reaction pathway involving propargyl amines as intermediates that do not undergo rearrangement is presented. The formation of indolizines or chalcones is driven by inductive and solvent effects, with a wide array of both being reported. In both reactions, the nanoparticulate catalyst has been shown to be superior to some commercially available copper catalysts
