Abstract

The utility of novel Fe₃O₄@Au nanoparticles as magnetically separable and recyclable heterogeneous catalysts for the A³-coupling reaction of aldehydes, amines and terminal alkynes to yield the corresponding propargylamines is demonstrated. Herein we present a comprehensive analysis of the experimentally observed trends in the conversions with computational analysis using LUMO density on molecular isosurfaces and the electrostatic potential (ESP) effects estimated using DFT calculations.
