Abstract

A robust, safe and magnetically recoverable Fe₃O₄ nanoparticle catalyzed three-component coupling of aldehyde, alkyne, and amine (A³-coupling) was developed. A diverse range of propargylamines were obtained in moderate to high yield under mild conditions in air. The separation and reuse of the magnetic Fe₃O₄ nanoparticles were very simple, effective and economical.
