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 (1(3-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.
