Abstract

A novel paramagnetic ionic liquid, 3-(2-hydroxyethyl)-1-methyl imidazolium bromotrichloro ferrate (III), was synthesized and exhibited high catalytic performance in the synthesis of 1-amidoalkyl-2-naphthols via one-pot three-component condensation reaction of aromatic aldehydes, 2-naphthol and acetamide at 85°C under solvent-free conditions. The catalyst showed response to an external magnet and was characterized by Fourier transform infrared spectroscopy (FT-IR), UV–Visible spectroscopy, Thermal gravimetric analysis (TGA) and Raman spectroscopy.
