Clean Synthesis of Propargylamines Using Novel Magnetically Recyclable Silver Nanocatalyst (AgMNPs)

Abstract

A novel and green magnetic nanocatalyst were synthesized by anchoring silver (I) to (2-iminomethyl)pyridine moiety. The prepared nanocatalyst was identified by different techniques, such as FT-IR, XRD, SEM, EDX, VSM, and TGA analyses. The nanocatalyst exhibited significant catalytic activity and recoverability in a three-component coupling reaction of aldehyde, amine, and terminal alkyne to produce a variety of propargylmines. This impactful method furnished the desired products under mild reaction conditions, in excellent yield (91–98%) and lower reaction time (25–45 min). The nanocatalyst was easily recovered by an external magnet and reused in10 consecutive cycles without a considerable decrease in its activity and selectivity.
