DABCO-based ionic liquid-modified magnetic nanoparticles supported gold as an efficient catalyst for A3 coupling reaction in water

In this work, a new heterogeneous catalyst, comprising gold supported on DABCO-triazole ionic liquid-modified magnetic nanoparticles (Fe3O4@DT-Au), is developed for A3-coupling reaction. This nano-catalyst characterized using different techniques, such as TEM, SEM, SEM-elemental mapping, XRD, XPS, and TGA. Using 0.05 mol% of the three-component reaction amines, aldehydes alkynes efficiently performed at 40 °C in water. catalyst easily recovered recycled through external forces six times with small decrease activity re-used was characterized.
