چکیده
|
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.
