  4. Abstract:
  5. An eco-friendly gold-based catalyst supported on proline decorated montmorillonite was synthesized. The catalyst was characterized by combination of Fourier-transform infrared spectroscopy (FT-IR), Field Emission Scanning Electron Microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Brunauer–Emmett Teller (BET) surface area analysis, Ultraviolet–visible spectroscopy (UV-Vis), Energy-dispersive X-ray spectroscopy (EDX), thermo gravimetric analysis (TGA) and atomic absorption spectroscopy (AAS) techniques. The synthesized catalyst was found to be a highly efficient heterogeneous nanocatalyst for multi component A3 coupling reaction of aldehyde, amine and alkyne in water as a green solvent at room temperature. This novel catalyst promotes multicomponent reaction of a large library of functional substrates under mild and sustainable conditions (water as a green solvent at ambient temperature). In addition, the catalyst could be easily recovered by simple filtration and reused for at least 6 cycles without losing its activity. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim
