Bis (1(3-trimethoxysilylpropyl)-3-methyl-imidazolium) copper tetrachloride attached to colloidal silica nanoparticles as an efficient catalyst for the preparation of propargylamines

چکیده مقاله

In this research, we reported the successful preparation of bis (1(3- trimethoxysilylpropyl)-3-methyl-imidazolium) copper tetrachloride tethered to colloidal silica nanoparticles and investigated its catalytic application for one-pot multicomponent preparation of propargylamines under microwave irradiation. Ionic liquid tethered to colloidal silica nanoparticles have been characterized by H NMR spectroscopy, scanning electron microscopy, energy dispersive spectroscopy, thermogravimetric analysis, and dynamic light scattering.
