A magnetic nanoparticle-supported sulfuric acid as a highly efficient and reusable catalyst for rapid synthesis of amidoalkyl naphthols
2013
Safari, Javad | Zarnegar, Zohre
Sulfuric acid functionalized magnetic Fe₃O₄ nanoparticles (MNPs-SO₃H) efficiently catalyze one-pot multicomponent condensation of β-naphthol with aromatic and aliphatic aldehydes and amide derivatives under solvent-free conditions to afford the corresponding amidoalkyl naphthols in excellent yields and in very short reaction times. High catalytic activity and ease of recovery using an external magnetic field are additional eco-friendly attributes of this catalytic system.
