Abstract

The preparation of trans-dihydrofurans has been achieved by a one-pot condensation reaction of 4-bromophenacyl bromide, aromatic aldehydes and 5,5-dimethyl-1,3-cyclohexanedione using bis 13-trimethoxysilylpropyl-3-methyl-imidazolium copper tetrachloride tethered to colloidal silica nanoparticles under microwave irradiation. Ionic liquid tethered to colloidal silica nanoparticles have been characterized by H NMR spectroscopy, scanning electron microscope, energy dispersive spectroscopy, thermogravimetric analysis and dynamic light scattering.
