Abstract:Preparation and catalytic performance of nanosized copper particles supported on expanded
corn starch (ECS) was investigated. The catalyst was characterized by inductively coupled plasma optical
emission spectrometry (ICP-OES), X-ray powder diffraction (XRD), N2-sorption analysis, thermogravimetric
analysis (TGA), energy dispersive X-ray spectroscopy (EDS), and transmission electron
microscopy (TEM).
The copper nanoparticles supported on expanded corn starch (CuNPs@ECS) were found to be a very
efficient and durable catalyst for the preparation of propargylamines by three component reaction of
secondary amines, aldehydes and alkynes. The catalyst can be successfully recycled and reused without
significant loss of efficiency in 4 reaction runs. The procedure described here offers an easy and practical
method accompanied by higher yields, and environmentally benign system.
