A novel Iron-Containing Ionic Liquid as an efficient catalystfor the synthesis of ۱-amidoalkyl-۲-naphthols

Over the past decade, catalysis in ionic liquids (ILs) has experienced a tremendous growth, and there arenumerous examples of a variety of catalytic reactions that have been successfully carried out in such neotericmedia. In this study, a novel hydrophilic magnetic room temperature ionic liquid (RTMIL) ۴-(۱-hydroxyethyl)-۱-methylimidazolium bromo trichloroferrate(III) was synthesized by mixing ۴-(۱-hydroxyethyl)-۱-methylimidazolium bromide with FeCl۳. Then, the new magnetic ionic liquid (MIL) was characterized usingtechniques such as ultra violet(UV), Raman, Infrared(IR) and Mass spectroscopy and also thermal gravimetryanalysis (TGA). The catalytic activity of the MIL was probed through one-pot synthesis of ۱-amidoalkyl-۲-naphthols via one-pot three-component condensation reaction of ۲-naphthol, arylaldehydes and acetamide.
